Step-by-step explanation:

area of big circle is πr2

the diameter is 10 CM then the radius is d/2 =10/2=5

then area of big circle is 22/7×5×5

22×25/7

550/7

=78.5

the area of small circle is πr2

diameter is 4 CM

then radius is 2 CM

then area of small circle is 22/7×2×2

=88/7

=12.5

then the area of shaded region is equal to

area of big circle- area of small circle
