You solved this one so I'm not going to show the work for it.

15=B,C,D
a.-30(-3x+2)=90x-60- incorrect
b.30(-3x+2)=-90x+60
c.10(-9x+6)=-90x+60
d.-10(-9x-6)=90x+60
e.-10(9x+6)=-90x-60- incorrect

16=D
-18x-12-(-13x+17)
-18x-12+13x+17
-5x+5

17=C
9x+3-5x-7
4x-4

18=C
You solved this one...

19=B
8.4x+2.9+(-3.7x+5)
8.4x+2.9-3.7x+5
4.7x+7.9

20=C

21=D
D is the only one that ends with +32 and not -32, which would be incorrect.

22=Cant see >.<

23=A
4x+12+15-3x
x+27

24=B
2x+3

The volume of this right circular cylinder is 64π cubic yards. If h, the height of the cylinder, is 4 yards, what is r, the radi
sergiy2304 [10]

Answer:

h = 4 cm

Step-by-step explanation:

The formula for volume of a cylinder is

V = πr²h      where V is the volume, r is the radius, and h is the height.

We are given V = 64π, and r = 4, plug those in and solve for h

64π = π(4²)h

64π = 16πh

(64π)/(16π) = (16πh)/(16π)      (divide both sides by 16π)

4 = (16π)/(16π)h

 4 = h
