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? (Pi = 3.14)

area of quarter cirle=1/4*pi*r^2=25pi
area of rectangle=48
Shaded area=25pi-48=30.5 smile12
