Which is the correct first step in finding the area of the base of a cylinder with a volume of 140 pi cubic meters and a height of 12 meters?
V = B h. 12 = B (140 pi)
V = B h. V = 140 pi + (12)
V = B h. V = 140 pi (12)
V = B h. 140 pi = B (12)

140π=b*12

Don't bother about the stuff below.

Step-by-step explanation:

The formula for the volume of a cylinder is 2πr²h. In this case, we'd put it as:

(Making π=3.14)

2πr²*12=140π

6.28*r²*12=439.6

75.36*r²=439.6

Divide both sides by 75.36

r²≈5.83

(3x-8) or (3x+8)
