What is the volume of a hat box (cylinder) in liters, which is 60.0cm in diameter and 38.5cmtall ? (V = πr2h) Explain how you got your answer.

The volume of air in one beach ball is 972? in3. What is the volume of air in a ball whose radius is 3 inches greater than the first beach ball? A beach ball is spherical in shape. Recall that the formula for the volume V of a sphere where r is the radius is given by the following formula. V=4/3?r3 It is given that the volume of the first beach ball is 972? in3. Substitute this value for V in the volume formula for a sphere. ______= 4/3?r3
