###### Exercise66

A cylinder’s volume can be calculated by the formula $$V=\pi r^2h\text{,}$$ where $$V$$ stands for volume, $$r$$ for the base radius and $$h$$ for the cylinder’s height.

Use the formula to calculate the cylinder’s volume if its base’s radius is $${5\ {\rm m}}\text{,}$$ and its height is $${10\ {\rm m}}\text{.}$$

1. This cylinder’s volume, in terms of $$\pi\text{,}$$ is .

2. This cylinder’s volume, rounded to the hundredth place, is .
