Volume and Surface Area of Cones and Spheres WORKSHEET
Volume and Surface Area of Cones and Spheres WORKSHEET DESCRIPTION
This worksheet provides a comprehensive selection of questions involving the volume and surface area of cones and spheres.
In section A, learners will need to be able to find both the volume and surface area for given spheres, cones and a compound shape made from a cone and hemisphere. They will also need to work backwards to find the radius of a sphere with a given volume or surface area.
Section B then asks learners to use the sectors and circles that would be the nets of cones – they will need to think about how to find the height of the cone, the radius of the cone or the angle of the sector.
All worksheets are created by the team of experienced teachers at Cazoom Maths.

Frequently Asked Questions
Students should be confident with finding the area of circles and sectors, as these skills are essential for calculating surface areas of spheres and the curved surfaces of cones. They'll also need a solid understanding of Pythagoras' Theorem, particularly when working with cone nets where they need to find missing dimensions like height or slant height.
