What is the radius of 1017.36 if i already did the area?

The question is stated as if in the presence of excessive background noise.

If we're talking about a circle, and if '1,017.36' is its area, then we can find the radius like this:

1,017.36 = pi R2

Divide each side by pi:

1,017.36 / pi = R2

Take the square root of each side:

R = sqrt( 1,017.36 / pi ) = 17.99544(rounded)

=====================================

We're guessing that the given radius was 18, and some arithmetic errors crept in

during the process of finding the area.

If the radius is 18, then

Area = pi R2 = 324 pi = 1,017.88 (rounded)

Working backward from 1,017.88, we would get 18.00004 for the radius.
