Answer:
See explanations below
Step-by-step 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
