Question

What is the volume of a cylinder with a height of 2.3 in and a base with a diameter of 15.2 in, to the nearest tenth of a cubic inch?​

Answer 1

if the diameter of the its base is 15.2, then its radius is half that, or 7.6.

`\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ h=2.3\\ r=7.6 \end{cases}\implies V=\pi (7.6)^2(2.3)\implies V\approx 417.4~in^3`
