find the volume of a sphere that has a diameter of 12 cm.
please show me how to work this problem


Hi Stephanie,

The volume of a sphere is given by the expression

volume = 4/3 r3

where r is the radius of the sphere and is approximately 3.1416. Your sphere has diameter 12 cm and the radius is half the diameter, so the radius id 6 cm. Hence the volume is

 4/3 r3 =  4/3 3.1416 63 = 904.78 cubic centimeters.
