Question

The radius of a cylinder is 6 in and the height is 9 in. What is the exact volume of the cylinder? 108π in³ 216π in³ 324π in³ I don't know.

Answer 1

`\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=6\\ h=9 \end{cases}\implies V=\pi (6)^2(9)\implies V=324\pi~in^3`
