A cylinder has a radius of 3 inches and a height of 6imches .What is the volume?
Answer:
-The volume of a cylinder can be either:
In terms of pi: [tex]54\pi[/tex]
or
Using 3.14 for pi: [tex]169.646[/tex] [tex]in^3[/tex]
Step-by-step explanation:
Use the formula for the volume of a cylinder and use the given radius and height for the formula:
[tex]V = \pi r^2 h[/tex]
[tex]V = \pi 3^26[/tex]
Then, solve the formula:
[tex]V = \pi \times 3^2 \times 6[/tex]
[tex]V = \pi \times 9 \times 6[/tex]
[tex]V = \pi \times 54[/tex]
[tex]V = 54\pi \approx 169.646[/tex]
-So, the answers would be:
In terms of pi: [tex]54\pi[/tex]
or
Using 3.14 for pi: [tex]169.646[/tex] [tex]in^3[/tex]
Answer:
169.65 inches^2
Step-by-step explanation:
Volume of a cylinder
V = pi x r^2 x h
pi x 3^2 x 6
≈ 169.65

where [tex]2\pi[/tex] represent [tex]360^{\circ}[/tex]
solve for x
4(2x-1)= 3x-19
Answer:
x = -3
Step-by-step explanation:
In an equation our aim is to find the value of what we are looking for as well as keeping the equation balanced. For example if we took away 4 only from one side then the equation would change so it's an important rule to keep in mind when solving equations, that you need to keep both sides of the equation the same.
4 ( 2x - 1 ) = 3x - 19
→ Expand the brackets
8x - 4 = 3x - 19
→ Minus 3x from both sides to isolate -19 and bring all the x coefficients to one side
5x - 4 = -19
→ Add -4 to both sides to isolate 5x
5x = -15
→ Divide both sides by 5 to isolate x and therefore find the value of x
x = -3
→ We can substitute x = -3 back into 4 ( 2x - 1 ) = 3x - 19 to see if we have the correct solution, if we end with the same number on both sides then x = -3 is correct.
4 ( 2x - 1 ) = 3x - 19
8x - 4 = 3x - 19
( 8 × -3 ) - 4 = ( 3 × -3 ) - 19
-24 - 4 = - 9 - 19
-28 = -28
So x = -3 is correct
Susie has $95 to spend on renting snorkeling gear at the beach. There is a $15 flat service fee to rent the snorkeling gear along with an $8 charge for each hour the gear is used. The inequality that can be used to find the number of hours Susie can rent the snorkeling gear is 15 + 8h ≤ 95. Calculate the maximum number of hours Susie can rent the snorkeling gear.
Answer:
10 hours
Step-by-step explanation:
We can actually solve this problem simply as if it were an equation instead of an inequality. We have:
15 + 8h ≤ 95
Subtract 15 from both sides:
8h ≤ 95 - 15
8h ≤ 80
Divide by 8 from both sides:
h ≤ 80/8
h ≤ 10
So, the number of hours cannot exceed 10, which means the maximum number of hours Susie can rent is 10 hours.

Dylan is wrapping a birthday present for his sister. The box the gift is in has a length of 6 inches, a width of 5 inches,
and a height of 3 inches. What is the minimum amount of wrapping paper Dylan will need to completely cover the
box?
TI
Answer:
126 square inches of wrapping paper
Step-by-step explanation:
To compute for the minimum amount of wrapping paper Dylan will need to completely cover the box, you have to compute the surface area of the box. The formula in getting the surface area of a rectangle is:
A = 2WL + 2LH + 2HW
Substituting the given measurements to the formula:
A = 2(5)(6) + 2(6)(3) + 2(3)(5)
A = 60 + 36 + 30
A = 126 square inches
Therefore, Dylan needs to purchase at least 126 square inches of wrapping paper to completely cover the box.

Step-by-step explanation:
The sum of the interior angles of a polygon is 8280°.
How many sides does the polygon have?
The equation to find the sum of interior angles of a n-sided polygon is:
(n - 2) * 180
So, we don't know what n is but we can make it look like this:
(n - 2) * 180 = 8,280
Solve for n.
(n - 2) * 180 = 8,280
~Divide 180 to both sides
(n - 2) * 180/180 = 8,280/180
~Simplify
n - 2 = 46
~Add 2 to both sides
n - 2 + 2 = 46 + 2
~Simplify
n = 48
Therefore, the polygon has 48 sides.
Best of Luck!
Sumiko and Chung are shopping. Chung wants to buy a video game that costs $60, and Sumiko wants to buy a new pair of sunglasses for $80. In their possession, they have a gift card for $20 dollars, applied after taxes, and a 15 percent off coupon, applied before taxes. Sumiko and Chung want to use their remaining money to buy lunch, which they will split, at the mall. Assuming that taxes are 8.7 percent, who should use which savings option to ensure they have the most money remaining for lunch?
Answer:
1.83
Step-by-step explanation:
First, add the game and glasses. Write down the number you just got. Now, multiply by 0.15.
Take the second away from the first.
Now multiply that by 0.087

PLEASE HELP ME 40 POINTS
Answer:
see below
Step-by-step explanation:
A: radius of 12 ft
Changing to meter
12 ft * .305 m/ ft =3.66 meter
The radius is 3.66 meters
The diameter is twice the radius = 2*3.66 =7.32 meters
The circumference is
C = pi*d = 3.14 * 7.32 =22.9848 = 22.98 meters
B diameter is 7.5 meters
Pool B has a bigger diameter
C = pi * d = 3.14 * 7.5m = 23.55 meters
The difference is .57 meters
Answer:
7.32
B
Larger/greater
0.57
Step-by-step explanation:
Diameter = 2 × radius
= 2 × 12 = 24 feet
24 × 0.305 = 7.32 meters
7.5 > 7.32
So the diameter of pool B is greater
Difference in circumferences:
(3.14 × 7.5) - (3.14 × 7.32)
23.55 - 22.98
0.57 meters

Bailey jog 3 km to her friends house from her friends house she jog 250m in all going to and from the park, then she jogged back home . How many meters did Bailey jogged in all
Answer:
The total distance is [tex]d_T = 6250 \ m[/tex]
Step-by-step explanation:
From the question we are told that
The distance from bailey start point to her friends house is [tex]d = 3 \ km = 3*1000 = 3000 \ m[/tex]
The distance covered going to and from the park is [tex]d_2 = 250 m[/tex]
The total distance covered is mathematically evaluated as
[tex]d_T = (2 * d_1) + d_2[/tex]
Substituting values
[tex]d_T = (2 * 3000) + 250[/tex]
[tex]d_T = 6250 \ m[/tex]

You can use the sine rule
a / sinA = b / sinB
Substitute the values in:
15 / sin112 = b / sin33
Multiply both sides by sin(33) to get b by itself
b = (15 / sin112) x sin33
Calculate this to get your answer of:
BC = 8.8 cm
2.
You can also use the sine rule here
sinA / a = sinB / b
Sub your values in:
sin84 / 32.4 = sin(y) / 21
Multiply both sides by 21 to isolate sin(y)
(sin84 / 32.4) x 21 = sin(y)
Calculate sin(y)
sin(y) = 0.6445975248
You now need to sin-1 this value to get u:

thousandth, if necessary.
Answer:
0.80

Consider the equation x 5 − 2 = 11. Each of these values might be the solution to this equation. Verify the correct solution by substituting each value into the equation. Which is the correct solution?
Answer:
x = 65
Step-by-step explanation:
Complete question is:
Which is the correct solution?
x = 1.8
x = 2.6
x = 45
x = 65
SOLUTION:
The given equation is : [tex]\frac{x}{5}-2=11[/tex]
Substituting all the values of 'x' one by one
-> For x = 1.8 : [tex]\frac{1.8}{5}-2=11[/tex]
-1.64≠11
-> For x = 2.6 : [tex]\frac{2.6}{5}-2=11[/tex]
-1.48≠11
-> For x = 45 : [tex]\frac{45}{5}-2=11[/tex]
7≠11
-> For x = 65 : [tex]\frac{65}{5}-2=11[/tex]
11=11
Therefore, by substituting x in every equation, x = 65

Substitute 7 for a.
Simplify the equation after substituting the value for a.
Verify that a = 7 is correct when the result is a true statement.
Step-by-step explanation:
Here, the given equation is,,
And, after solving it the result is,
a = 7
We can check whether a result is the solution of an equation by substituting the result in the given equation.
If we get a true statement, then the result is the solution of the equation.
Thus, for verifying the solution, steps are as follow,
Step 1 : Substitute 7 ,
-9(7-5) = -18
Step 2 : Simplify the equation after substituting the value of a
-9(2) = -18
Step 3 : Verify that a = 7 is correct when the result is a true statement.
-18 = -18

(ii) the y-intercept.

Answer:
(i) k =1
(ii) y-intercept is 7
Step-by-step explanation:
Given line:
ky = kx + x + 7Divide all terms by k to get slope-intercept form of the line
y = (1 + 1/k)x + 7/kSince the gradient (slope) of the line is 2:
1 + 1/k = 21/k = 1k = 1The equation is now:
y = 2x + 7y - intercept is found when x = 0
x = 0 ⇒ y = 2*0 + 7 y = 7What is the value of y if f(x)=-3?
