Draw a diagram of the problem. It'll help you see the problem.

Consider a circle of radius 8 yards, 3 yards, and 1 yard.
.
(3/4)(pi)(8^2) + (1/4)(pi)(3^2) + (1/4)(pi)(1^2)
(3/4)(pi)(64) + (1/4)(pi)(9) + (1/4)(pi)(1)
(192/4)(pi) + (9/4)(pi) + (1/4)(pi)
((192+9+1)/4)(pi)
(202/4)(pi)
(101/2)(pi)
(101/2)(3.14)
158.57 square yards
