Question

Math 80 how to get a radius from the area of a circleArea = 508

Answer 1

Given:

`A=508\text{ square units}`

Using the area of a circle,

`A=\pi r^2`

Hence,

`\begin{gathered} 508=\pi* r^2 \\ (508)/(\pi)=r^2 \\ r=\sqrt{(508)/(\pi)} \\ r=12.716 \\ r\approx12.72 \end{gathered}`

Therefore, the radius is approximately 12.72 units
