Find total area of pie using the diameter and the equation (3.14)r^2
Divide the total area by 8 and multiply by 7 to get the remaining pie.

henry2,
A1 = pi * r^2 = 3.14 * 7^2 = 153.86 in^2 = area before it was cut.
A2 = A1 - A1/8 = 153.86 - 153.86/8 = area remaining.
A2 = A1 - A1/8 = 153.86 - 153.86/8 = area remaining.
