Worksheet Overview

The formula for the volume of a sphere, V, in terms of its radius, r, is:


V = 4/3πr3



Calculate the volume of the sphere shown below in cm3 to 3 sig. figs.


 sphere of diameter 8 cm



Diameter d = 8 cm

Radius r = 8 ÷ 2 = 4 cm


Volume =  4/3πr3 = 4 ÷ 3 x π x 43  = 268.08.... ≈ 268 cm3 (3 s.f.)
