Example 1: Finding the Volume of a Sphere
Find the volume of a sphere with radius 12 cm, both in terms of p and to the nearest tenth. Use 3.14 for p. 4 3
V = pr3
Volume of a sphere
= p(12)3 4 3
Substitute 12 for r.
= 2304p cm3  7,234.6 cm3

3. Spheres 4 V = pr3 3 Volume of a sphere 4 = p(3)3 3 Substitute 3 for r.

Spheres
Example 1
Find the volume of a sphere with radius 3 m, both in terms of p and to the nearest tenth. Use 3.14 for p. 4 3
V = pr3
Volume of a sphere
= p(3)3 4 3
Substitute 3 for r.
= 36p m3  m3
