Question

If the radius of the base is 2, and the height is 4, what is the volume of the cylinder?

Answer 1

The volume of the cylinder would be approximately 50.29 if you use 22/7 for pi.
I have attached a picture of the work. I hope this helps. (:

Answer 2

givens
pi = 3.14
r = 2
h = 4

Formula
v = pi r^2 h

Sub and Solve
V = 3.14 * 2^2 * 4
V = 3.14 * 4 * 4
V = 3.14 * 16
V = 50.24
