Answer:

37.7 sq units

Explanation:

Find area if entire region then subtract out each smaller circle

Diameter of entire circle would be 3(2)+2(2) which is 10 so radius is 5

Area of entire region = 25π

Area of circle one = 9π

Area of circle two = 4π

Area of shaded region = 25π - 13π which is 12π or 37.7

Answer:

area of circle having radius 3

is πr²=π*3²=9π square units

area of circle having radius 2

=πr²=π×2²=4π square units

again

area of big circle having radius [3+2]=5 units

=πr²=π×5²=25π square units

Now

area of shaded region=25π-4π-9π=12π or 37.7square units.
