Calculate the volume and surface area of a sphere:

Calculate the volume and surface area of a sphere with r = 4".  Be sure to include units in your answer.

Solution:

V = 4/3πr3                                           SA = 4 πr2

V = 4/3 π(4)(4)(4)                               SA = 4 π(4)(4)

V = 4.2(64)                                         SA = 12.6(16)

V = 268.8 cubic inches                       SA = 201.6 square inches
