 # Volumes of Spheres

In this worksheet, children must calculate the volume of spheres, given their radii or diameters. Key stage:  KS 3

Curriculum topic:   Geometry and Measures

Curriculum subtopic:   Use 3D Shape Knowledge to Solve Problems

Difficulty level:   ### QUESTION 1 of 10

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

V = 4/3πr3

Example

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

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