Question

The volume of a cylinder is 540_ ft3. The height is 15 ft. What is the diameter of the cylinder?

A. 6 ft
B. 12 ft
C. 24 ft
D. 36 ft

Answer 1

I hope this helps you



Volume =pi.r^2.h



540.pi=pi.r^2.15


r^2=36


r=6

Answer 2

Volume of a cilinger, V = π(r^2)H

Here, V = 540π ft^3 and H =15 ft

Then, r^2 = 540π ft^3 / [π15ft] = 36ft^2

r = √(36ft^2) = 6ft

And the diameter is 2*r = 12 ft
