Example 1: Finding the Volume of a Sphere Course 3 Spheres 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

Spheres 4 V = pr3 3 Volume of a sphere 4 = p(3)3 3 Substitute 3 for r. Course 3 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  113.0 m3
