Final answer:
The volume of a sphere with a radius of 6 units is 288Π units³.
Step-by-step explanation:
The volume of a sphere can be calculated using the formula V = (4/3)Πr³, where r is the radius of the sphere. In this case, the radius is 6 units, so substituting it into the formula gives V = (4/3)Π(6)³ = 288Π units³. Therefore, the correct answer is b) 288Π units³.
