Pie Are Square. Not round.
11 x 5 1/2 x 5 1/2 divided by 8.

Area = pi x r^2
Since r = d/2, r = 11/2
Area = pi(11/2)^2 or 121/4 pi
Now, divide by 8, or multiply by 1/8, so each piece's area is 121/32 pi

You multiply 3.14 times 5.5 times 5.5 and divide by 8 (for 8 slices). Pi time the radius squared gives the area of a circle, then you divide by the pieces.
You can do the math.

Area of whole pie = pi*(11/2)^2 = 95.03 square inches
95.03 / 8 pieces= 11.9 square inches

ok, you figure the area of the pie 2pi r squared
or the diameter times pi (not pie) squared. Then divide by 8
pi = about 3.14159
