Question

Find the formula
Plug in values
Volume

Answer 1

See explanations below

Explanation:

Volume of the sphere is expressed as;

V = 4/3πr³

r is the radius

V = 4/3 * 3.14 * 3³

V = 4/3 * 3.14 * 27

V = 4 * 3.14 * 9

V = 113.04cube units

For the secind sphere;

diameter = 12

radius = 12/2 = 6

V = 4/3πr³

r is the radius

V = 4/3 * 3.14 * 6³

V = 4/3 * 3.14 * 216

V = 4 * 3.14 * 72

V = 904.32cube units
