Volume of spheres, pyramids & cones

Me and Atif are working on a solution to the problems: calculating the volume of spheres, pyramids and cones.

The question is 'A metal cone is melted down and made into 100 ball bearings. If the cone has a base diameter of 8cm and height of 7cm, what is the radius of one ball bearing?


  1. Well done boys, you got a tough topic there! That example question is at about GCSE Grade B level!
