Answer: 1846.32 cubic feet
==================================================
Work Shown:
V = pi*r^2*h is the volume of any cylinder with radius r, height h
r = 7, h = 12
Plugging those values in gets us this
V = pi*7^2*12
V = pi*49*12
V = pi*588
V = 588*pi
We will use 3.14 for pi, so we replace pi with this value
V = 588*3.14
V = 1846.32
The units for the volume are in cubic feet. We can abbreviate this to ft^3.
