###### Exercise60

A circle’s circumference formula is \(C=2\pi r\text{,}\) where \(C\) stands for circumference and \(r\) for radius. And a circle’s area formula is \(A=\pi r^2\text{,}\) where \(A\) stands for area and \(r\) for radius.

Use those two formulas to answer the following questions about a circle with radius \({5\ {\rm m}}\text{.}\)

This circle’s circumference, in terms of \(\pi\text{,}\) is .

This circle’s circumference, rounded to the hundredth place, is .

This circle’s area, in terms of \(\pi\text{,}\) is .

This circle’s area, rounded to the hundredth place, is .
