I think you forgot to give the diagram along with the question. Considering 8 ft as the radius, we can find the area by the formula described below. Area = pi * (Radius) ^2 = 3.14 * (8)^2 = 3.14 * 64 = 200.96 So the area of the shaded portion would be 200.96 square feet. I hope that this answer has come to your help.
