Volumes

I have been struggling with question for quite sometime, can anyone help me out?

A cylindrical jar of radius 14 cm is filled with water up to a height of 24 cm. 14 spherical balls of radius 2 cm each are immersed in the jar. find the new level to which water is filed in the jar.

Thanks.

1) What is the volume of a cylinder of radius 14 cm and height 24 cm? That is the volume of the water.

2) What is the volume of a single sphere of radius 2 cm?

3) What is the volume of 14 such spheres?

4) So what is the total volume of the water and 14 spheres?

5) Since that is all contained in a cylinder of radius 14 cm, what height in that cylinder will give that total volume?
