The area of EOF is a quarter of a circle with point O at the center of the circle. The line segment AC is 8 inches long and the line segment BC is 6 inches long.

How many square inches are in the shaded areas?

By Pythagoeas, OC = 10, therefore area of circle is 100*pi and area of quadricircle(?) OEF is 25*pi.

Hopefully this gives shaded area as 25*pi-48 = 30.5 approx
