ProfessorThe Men's Size 7 regulation basketball has a diameter of 9.39 inches and radius of 4.695 inches. The surface area is calculated using the formula (pi x r2 ) where pi = 3.142 and r is the radius.
Hernce, surface area = 3.142 x 4.6952 = 69.259 square inches.

Why sphere has minimum surface area for given volume?
The same volume of an object, The simplest regular tetrahedron polyhedron, calculate the surface area. The surface area is pentahedral small surface area than the regular tetrahedron Regular hexahedron surface area than the surface area is small pentahedral . . . .
