Question

A cylinder has a base diameter of 4 inches and a height of 4 inches. What is its volume in cubic inches, to the nearest tenths place?

Answer 1

V=πr2h=π·22·4≈50.26548

Explanation:

the first step is to get a radius that is 1/2 of diameter. So 4/2=2, r=2

then pi x 2^2 x 4 which gets you 50.265 or 20.27 if you round it
