use the formula for finding the area of a semi circle pi r^2
the radius is half the diameter, the diameter is given because a rectangle has 2 pairs of equal sides
1) pi 2.5^2=pi 6.25
2) pi 7^2= pi* 49
area rectangle=70cmsq
area small hemisphere=235.5cmsq
area big hemisphere=1846.32cmsq
adding all
2151.82 cmsq
