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
=78.5-12.5
66cm
