would be very much appreciated

Area of a circle = (pi)(radius squared)

Find the area of the larger circle, then find the area of the smaller circle and then subtract the difference.

Larger Circle:
A=(3.142)(5cm)2
A=(3.142)(25)
A=78.55

Smaller Circle:
A=(3.142)(2)2
A=(3.142)(4)
A=12.57

Subtract difference between the 2:

78.55-12.57= 65.98 cm is the area of the shaded portion
