Question

What is the volume of a cylinder with a height of 8.9 in and a base with a diameter of14.8 in, to the nearest tenth of a cubic inch?

Answer 1

Volume of the cylinder is given by the formula

`V=\pi r^2h`

Here r = 14.8/2=7.4 and height , h= 8.9

Hence the volume is given by

`\begin{gathered} V=\pi*7.4*7.4*8.9 \\ =1530.322 \end{gathered}`

Hence the volume is 1530 cu.in to the nearest tenth.
