Question

Find the circumference of each circle. Round your answer to the nearest tenth. 8mi

Answer 1

The radius of the circle is r = 8.

The formula for the area of circle is,

`A=\pi\cdot(r)^2`

Substitute the value of r in the formula to determine the area of circle.

`\begin{gathered} A=\pi\cdot(8)^2 \\ =201.061 \\ \approx201.1 \end{gathered}`

So area of circle is 201.1 miles square.
