Since the diameter of the sphere is 4.35, it means the radius is 2.175.
A = 4 x pi x r^2 => 4 x pi x 2.175^2 = 18.923 pi sq in.
1 sq in = 6.452 cm^2 => 18.923 x 6.452 = 122.091pi sq cm
V = 4/3 x pi x r^3 = 4/3 x pi x 2.175^3 = 13.719 pi cu in.
1 cu in = 16.387 cn^3 => 13.719 x 16.387 = 224.813pi cu cm
