A cylinder has a radius of 2 feet and a height of 18 feet.
Volume (to the nearest tenth) = a0 cubic feet
i TRIED to work out this problem. The answer I got was 226.3 I used the cylinder volume formula which is π r2 h.!
The computer says my answer is wrong. what am I doing wrong?

V = pi * r^2 * h
V = 3.14 * 4 * 18
V = 226.08 = 226.1
