Question

What is the volume, in cubic meters, of a cylinder with a height of 4 meters and a base radius of 7 meters, to the nearest tenths place?

Answer 1

V= pi times (7 squared) times 4

Answer 2

`\bf \textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ r=7\\ h=4 \end{cases}\implies V=\pi (7)^2(4) \implies \stackrel{\textit{rounded up}}{V=615.8}`
