Answer:
Height of the cylinder is 1ft
Step-by-step explanation:
Data ;
Volume = 314ft³
Assuming radius = 10ft
Height = ?
π = 3.14
Volume of a cylinder = πr²h
r = radius
h = height of the cylinder
Vol = πr²h
314 = 3.14 × 10² × h
314 = 314h
Solve for h,
h = 314 / 314
h = 1ft
The height of the cylinder is 1ft.

A customer deposits $500 in an account that pays 4% annual interest. What is the balance after 3 years if the interest is compounded annually? Compound interest formula: V (t) = P (1 + StartFraction r Over n EndFraction) Superscript n t t = years since initial deposit n = number of times compounded per year r = annual interest rate (as a decimal) P = initial (principal) investment V(t) = value of investment after t years
Answer:
$562.43
Step-by-step explanation:
V(3) = [tex]500 ( 1 + \frac{0.04}{1} )^{3} \\500 (1.04)^{3}[/tex]
= 562.43
The interest is $562.4 compounded annually.
What is Compound interest?Compound interest is defined as interest paid on the original principal and the interest earn on interest of principal.
P = $500
r = 4%
t = 3 years
CI = P( 1+ r/100)ⁿ
CI = 500 ( 1+ 4/100)³
CI = 500 ( 1+ 0.04)³
CI = 500 ( 1.04)³
CI = 500 ( 1.1248)
CI = 562.4
Hence, the interest is $562.4 compounded annually.

Answer:
1) 30 units³
2) 18 units³
Step-by-step explanation:
1) The formula for volume is v = height x length x width
The height of the first object is 2, the length is 5, and the width is 3. 2 x 5 x 3 is 30, so the volume is 30 units ³.
2) Use the same formula, v = h x l x w
The height is 3, the length is 3, and the width is 2.
3 x 3 x 2 = 18
So the volume is 18 units³.
Note: Find each of the values by counting the number of squares
Find the missing angle. *
70°
?
40°
40 degrees
100 degrees
25 degrees
70 degrees
Answer:
70
Step-by-step explanation:
A triangle angles add up to 180 so you add up 70 and 40 and then subtract that answer from 180 and you get 70
Answer:
70 degrees.
All three sides of a triangle added together will equal 180 degrees. If 70 and 40 are added together then you get 110. Then you subtract the total 180 and the two angles that equal 110. You get 70 degrees, which is your missing angle.
A store sells a coat in three sizes: small, medium and large. The coat comes in red, navy, and tan. Sales numbers are shown in the table.
Find the probability that the next coat sold is a medium.
Write your answer in reduced fraction form.
Answer:
Next coat sold as medium: 68/190 (35.79%) Rounded to the nearest hundredth) or reduced fraction form of 34/95.
Step-by-step explanation:
Red Medium: 21/58 ( 36.21%)
Navy Medium: 22/66 (33.33%
Tan Medium: 25/66 (37.88%)
Since it's asking for the probability that the next coat is a medium, no matter the color, we add in all numbers and divide it by the added medium from all three colors.
Next coat sold as medium: 68/190 (35.79%) Rounded to the nearest hundredth) or reduced fraction form of 34/95.

: A marker in the shape of a cylinder has a diameter of 14 mm and a height of 136 mm. Find the volume of the figure described. Use 3.14 for . Round your answer to the nearest tenth, if necessary. *
Answer:
The volume of the figure is 20,925.0mm^3.
Step-by-step explanation:
Firstly we know that the Diameter = 14mm and Height = 136mm.
Area of Circle = 3.14xR^2 Radius = Diameter / 2
Area of Circle = 3.14x7mm^2 = 153.86mm
Volume = 153.86 x 136 = 20,924.96
Then round, to get 20,925.0
Let me know if this is helpful
Answer:
Volume : ( About ) 20925 mm^3
Step-by-step explanation:
1. If the diameter of this cylinder is 14 mm, the radius ⇒ 14/2 ⇒ 7 mm
2. Now knowing the radius, it would be most convenient to solve for the Base, which is in fact a circle. As we can see, the general Volume of a 3-dimensional figure is Base * height, so this will be helpful. Applying πr^2, Base Area ⇒ π * ( 7 )^2 ⇒ π * 49 π ⇒ 153.86 mm^2
This means that the Volume would be ⇒ Base Area * height ( where height is 138 mm ) ⇒ 153.86 mm^2 * 136 mm ⇒ 20924.96 mm^3
Answer ( Volume ) : ( About ) 20925 mm^3
find the value of x
Answer:
Step-by-step explanation:
Here we have the length of the hypotenuse (16) and that of the vertical leg (11). The cosine function inputs this data:
adjacent side 11
sin x = ----------------------- = ---------------- = 0.6875
hypotenuse 16
We find x using the arccos function: arccos 0.6875 = 0.81 radians or
46.57 degrees
A square pyramid has a base with a total area of 144m^2 and a volume of 384m^3, what is the slant height of the pyramid?
Answer:
8mStep-by-step explanation:
Volume of a square based pyramid = [tex]\frac{1}{3}a^{2}h[/tex] where;
a² is the base area of the pyramid since it is square shaped
h is the slant height.
Given Base area = 144m² and Volume = 384m³, on substituting this values given in the formula we have;
[tex]384 = \frac{1}{3}*144h \\cross\ multiplying\ \\384*3=144h\\h = \frac{384*3}{144} \\h = \frac{1,152}{144}\\ h = 8m[/tex]
The slant height of the pyramid is 8m

3 out of 5 students say yes if there are 105 students how many say yes
Answer:
63 students said yes.
Step-by-step explanation:
105/5= 21
21*3= 63
Answer:
C = 63
Step-by-step explanation:
We know that there are 105 students, so we will take the total amount of students and multiply by 3/5, since this is the probably rate is which say yes. in other words --> 105 * 3/5 = 63

A square has sides of length 15. What is the length of the diagonal?
А
14/4
B
15/2
C
16/5
D
12/3
Answer:
15 sqrt(2) =c
Step-by-step explanation:
We can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
The legs are 15 and the hypotenuse is the diagonal
15^2 + 15^2 = c^2
2 * 15^2 = c^2
Take the square root of each side
sqrt(2 * 15^2 )=sqrt( c^2)
sqrt(2) sqrt(15^2) = c
15 sqrt(2) =c
Answer: 15[tex]\sqrt{2}[/tex] (b)
Step-by-step explanation:
You can separate a square into two different 45-45-90 degree triangles.
Where x = 15, and the diagonal would be the hypotenuse.
So, here you can use the Pythagorean Theorem to find the hypotenuse to use 45-45-90 triangle theorem where they hypotenuse is always x times [tex]\sqrt{2}[/tex]
So, the diagonal would be 15[tex]\sqrt{2}[/tex]
