Question

Find the radius of a circle with an area of 529π square inches.

Answer 1

Explanation:

Given

Area (A) = 529
`\pi` square inch

radius(r) =?

Now

we have the formula

`\pi r^(2) = area`

`\pi r^(2) = 529\pi`

Both pie will be cancelled and we get

`r^(2) = 529`

`r =√(529)`

r = 23 inch
