Answer:

Larger shaded area = 48pi m^2 and

the small circle has area 4pi m^2.

If you require the as decimal values they are

150.80 m^2 and 12.57 m^2 to the nearest hundredth.

Explanation:

The area of the whole circle = pi r^2 = pi 8^2 = 64pi.

The area of the middle sized circle = pi 4*2 = 16pi.

So the area of the larger shaded region

= 64pi - 16pi = 48pi m^2.

The area of the small circle = pi r^2 = 2^2 pi = 4pi m^2.
