I1. The volume of spheres

A sphere is a closed surface that is the locus of all points that are a fixed distance (the radius) from a fixed point (the centre). For a sphere of radius r, the volume is given by the formula: An example A sphere has a radius of 4cm, find its volume.

Find the volume, correct to the nearest whole number, of each sphere. Click on "Sphere radius" to get started. Volume= cm³
