I’ll give the

the center of the circles in the figure is point o. what’s the area of the shaded region if the outside diameter (d) is 36 yards and the inside diameter (d) is 16 yards?

  816.816 yd²

Step-by-step explanation:

The outer circle has a radius of 18 yards, so an area of ...

  A = πr² = π(18 yd)² = 324π yd²

The inner circle has a radius of 8 yards, so an area of ...

  A = πr² = π(8 yd)² = 64π yd²

Then the shaded area is the difference of these, or ...

  (324π -64π) yd² = 260π yd² ≈ 816.816 yd²

16.80 times .20= 3.36
