Question 63448: A little league team is building a backstop for its practice field. It is made up of two right angles . The backstop extends 24 feet 8 inches out each direction and the center pole is 6.5 yards high. all sides of the backstop including base and center pole are to be made of aluminum tubing. How many feet of tubing should the team buy?How many square feet of the backstop must be covered by a screen?

Question 4 only
The ball radius is 5cm so its diameter is 10 cm. The balls on top of each other will give a height of the container of 30 cm.
Volume of a sphere formula can be used to find the volume of the tennis balls.
V=4%2F3%2API%2Ar%5E3
V=4%2F3%2API%2A5%5E3
=524 cubic cm
=1571 cubic cm for three balls
Vulume of a cylinder = area of base x height
PI%2Ar%5E2%2Ah
PI%2A5%5E2%2A30
=2356 cubic cm
The surrounding volume of area is the difference between the volume of the cylinder and the volume of the three balls.
2356-1571=785 cubic cm
