Answer:
2080
Step-by-step explanation:
The surface area of the cylinder is 2080π square feet. Answer: 2,080 pi feet squared.
What is a cylinder?A cylinder is a 3D solid form made up of two bases that are parallel and identical and are connected by a curving surface. These bases resemble spherical disks. The axis of the cylinder form is a line drawn through the center or connecting the centers of two circular bases.
The formula for the surface area of a cylinder is:
SA = 2πr² + 2πrh
where r is the radius of the base of the cylinder, h is the height of the cylinder, and π is the mathematical constant pi (approximately equal to 3.14159).
Since the diameter is given as 40 feet, the radius is half of that, or 20 feet.
So, substituting the values into the formula, we get:
SA = 2π(20)² + 2π(20)(32)
SA = 2π(400) + 2π(640)
SA = 800π + 1280π
SA = 2080π
Therefore, SA = 2080π.

On her first stroke, Maya hit a golf ball 146 yards, 2 feet, 11 inches. On her second stroke, she hit it 163 yards, 1 foot, 2
inches. How far did the ball go altogether? Convert the answer to larger units whenever possible.
A. 311 yards 11 inches
B. 310 yards, 1 foot, 1 inch
C. 309 yards, 3 feet, 13 inches
D. 309 yards, 1 foot, 1 inch
Answer:
A
Step-by-step explanation:
1 yard = 36 inches
1 feet = 2 foots = 24 inches
First time, she's got 5315 inches, second time is 5868 inches
5315 + 5868 = 11183 inches
11183 : 36 = 310.638888889 inches
Change it and we have answer A, 311 yards 11 inches

A student claims that if you dilate the net for a cube using a scale factor of 2, the surface
area of the resulting cube is multiplied by 4 and the volume is multiplied by 8. Does this
claim make sense?
(select)
make sense.
Answer:Yes
Step-by-step explanation:
Given
Suppose side length of cube is a
If we dilate the cube using a scale factor of 2
Side length becomes 2a
and the surface area becomes [tex]=6(\text{side length})^2[/tex]
Surface area[tex]=6(2a)^2[/tex]
Surface area[tex]=4\times 6(a)^2[/tex]
Thus surface area multiplied by a factor of 4
Now for volume
[tex]V=(\text{side length })^3[/tex]
[tex]V=(2a)^3[/tex]
[tex]V=8(a^3)[/tex]
Therefore volume is multiplied by a factor of 8
Therefore the above statements make sense

Answer:
Missing side = 2
X= 2
Have given details if x was only base of the side triangle
This is in order to find a completely new triangle with just the height and in order to find and combine 1 given area say if just the right side in your diagram was 4 and we had to find the other triangle. This is only done on scale or 1 given measure or angle for the right side triangle. We was not given this but proved a 0.3 scale.
Area of other triangle =2.66^2
2.66+4 combined = 6.66^2
Step-by-step explanation:
We find a square height is also 4
We also know a right angle triangles height can be found using either 1/2 base or 1/2 height.
So this can mean the height is and stays 4 and the base is 2.
As 1/2 4 height = 2 height
2 unit height x 2 unit base = 4
Therefore, the first triangle slant is the same.
4sq +2sq = c^2
√16+√4 = √20
c^2 = √20 = 4.47 = 4.472135955
c = 4.47 slant
Given a=4 and c=4.47,
b = 1.99522
∠α = 63.49° = 63°29'23"
∠β = 26.51° = 26°30'37"
h = 1.78543
We cna tell now that the triangle is 0.333 smaller so the measurements
Show 2/3 of 2 = 1.333 being the base across
using this as Area we find 1.333 x 2 = 2.666
(1/2 h^b of 4) =2
We can prove with the angles
63 +27 degree or
a^2+b^2 = c^2
1.333^2 + 4^2
= √1.776889+√ 16 = √ 17.776889
c^2 = 4.21626481616
c= 4.22 slant left side (nb right side on attachment)
Angle ∠ A = α = 71.478° = 71°28'39″
Angle ∠ B = β = 63.53° = 63°31'48″
Angle ∠ C = γ = 44.992° = 44°59'33″
We see 63 angle on right lower side of attachment picture in reflection and can prove x = 3.333
But on your diagram base x = 2
What i have done is enlarged x by 0.3 and proven how to find x if x was just one side of the triangle's height.
The triangles even though reflected are identical.
Other info is proven through finding ha and hb heights.
We confirm 4.001 is the hc height of your diagram.

The yearly percent change in the mass of the sample will be 81.06%.
What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred.
A sample of a mysterious chemical substance naturally gains mass over time.
The relationship between the elapsed time t, in years, since the mass of the sample, M(t), in grams, was initially measured is modeled by the following function:
[tex]\rm M(t) = (1.16)^{4t+3}[/tex]
The yearly percent change in the mass of the sample will be
At t = 0, we have
M(0) = (1.16)³ = 1.561
At t = 1, we have
M(1) = (1.16)⁷ = 2.826
Then the percentage will be
P = [(2.826 – 1.561) / 1.561] x 100
P = 0.8106 x 100
P = 81.06%

Find the zeros of the function f(x)=x2+2x-3
Answer:
x = -1 and x = 3
Step-by-step explanation:
f(x)= x^2-2x-3
f(x) = (x + 1) (x - 3)
Therefore, x = -1 and x = 3
The zeroes of the quadratic function f(x) = x² + 2x - 3 will be 1 and negative 3.
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2.
The quadratic equation is given below.
f(x) = x² + 2x - 3
Then the factor of the quadratic equation will be
f(x) = x² + 2x - 3
f(x) = x² + 3x - x - 3
f(x) = x(x + 3) - 1(x + 3)
f(x) = (x + 3)(x - 1)
The zeroes of the function will be
f(x) = 0
(x + 3)(x - 1) = 0
x = 1, -3
Then the zeroes of the quadratic function f(x) = x² + 2x - 3 will be 1 and negative 3.

Step-by-step explanation:
Solve the system algebraically. Check your work. 5x + 3y = 18 2x + 3y = 9 Make sure there are NO SPACES in your answer. Be sure to include a comma between the x and y values. ANSWER: {( a0 )}
Answer:
(3,1)
Step-by-step explanation:
5x + 3y = 18
2x + 3y = 9
So we can use elimination here to solve this system of equations by multiplying the second equation by -1
Now we have:
5x + 3y = 18
-2x - 3y = -9
Now we add straight down and combine like terms
The y terms cancel and we are left with 3x = 9, dividing both side by 3 we get x = 3
Now we can plug this x value into one of the original equations to solve for our y value
I will use the first equation: 5(3) + 3y = 18 → condensing the terms we get 15 + 3y = 18 → subtracting the 15 from both sides we get 3y = 3 → dividing both sides by 3 we get y = 1
The solution to this system of equations is (3, 1)
