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.

tried my best to show on that
Step-by-step explanation:
 
        
             
        
        
        
Using polynomial long division:
 (10n^2 - 37n - 12) divided by (n - 4) is
10n+3,

Shape A is congruent to Shape B because If you were to rotate one of the two and flip it the would like up and match.
