Question

Find the radius of a circle with an area of 89 square feet.

Answer 1

`r = 5.32\ feet`

Explanation:

Step 1: Determine the radius

Formula to get the area of a circle →
`A=\pi r^2`

Insert 89 into the A and solve for r

`(89)/(\pi) = (\pi r^2)/(\pi)`

`28.3296 = r^2`

`√(28.3295) = √(r^2)`

`r = 5.32`

Answer:
`r = 5.32\ feet`
