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.

=524 cubic cm
=1571 cubic cm for three balls
Vulume of a cylinder = area of base x height

=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
