It is best to solve for the areas of two circles and solve for their difference. The area is calculated by the equation, A = πd² / 4
                                   A1 = π x(9 ft)² / 4 = 81π/4 ft²
                                   A2 = π x(20 ft)² / 4 = 100π ft² 
The difference in their values is approximately 250.52 ft².
