Answer:
14
Explanation:
We are given the area of the circle and the formula as well. My phone doesn't have thr pi logo, so I'm gonna just type pi.
Just work backwards and solve for the radius, r.
658 sq ft is the area of the circle. We need to solve for r and we have to divide by pi first on both sides just to have r left as the only variable.
658 = pi × r × r
658/pi = r × r
Once we get the r by itself, we have to take the square root since the r is squared in the formula.
Hope this helps!
