Question

A tree trunk has a height of 30 feet and a radius of 2.5 what is the volume of the tree trunk

Answer 1

Check the picture below.

`\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=2.5\\ h=30 \end{cases}\implies V=\pi (2.5)^2(30)\implies V\approx 589.05~ft^3`
