## Basic College Mathematics (10th Edition)

First error is use $D$ instead $r$ Second error is that volumes units is cubic Correct answer $V = 3.14*3.5^2*5 = 192.3cm^3$
We have $D = 7cm$, $h = 5cm$ and $V = 3.14*7*7*5 = 769.3cm^2$ Volume formula for a cylinder is $V = 3.14*r^2*h$ So the first error is to use $D$ instead $r$ And the second error is that volumes units is cubic Correct answer $V = 3.14*3.5^2*5 = 192.3cm^3$
