The volume of a sphere with a radius of 11 cm is: 5,575 cm3
Volume of sphere is 5575.28 cubic units and its radius work out as 11 units rounded
A cone 11 inches high by 4 inches in diameter has a volume of 46.08 cubic inches.
4/3 x pi x 113 = 5575.28
Using the formula for the surface area of a sphere, which is SA = 4 (pi) r2, you can find the radius, and the diameter of the sphere is twice the radius. Example: If the surface of a sphere is 380 square cm 4 (pi) r2 = SA 4 (3.1416) r2 = 380 12.5664 r2 = 380 r2 = approx. 30.24 r = 5.5 and diameter D = 11 cm
