**tchrwill**, Monday, February 14, 2011 at 12:16pmBy equal size I assume you mean equal area. The total pie area is 3.14(8^2) = 201.06 sq.in. Each piece must therefore be 50.265 sq.in. in area.

The central piece is a circle with area = 50.265 = 3.14(r1)^2 making r1 = 4 in.

The next piece is a circular ring of r2 outer radius and r1 inner radius and area = 50.265 = 3.14(r2^2 - r1^2) making r2 = 5.656 in.

The next piece is a circular ring of r3 outer radius and r2 inner radius and area = 50.265 = 3.14(r3^2 - r^2) making r3 = ? Your turn.

The person getting the outer ring is cheated out of some cheese.
