Respuesta :

The volume of a sphere is equal to (4/3)pi*r^3

The volume of your sphere is then (4/3)*pi*r^3 = (4/3)*3.14159265*18^3 = 24429.024 cubic units. That is not one of the answer choices. The closest choice appears to be D.

Answer:

The volume of a sphere with a radius of 18 units will be 7776π units.

Step-by-step explanation:

VOLUME OF SPHERE

Volume of the sphere is the amount of quantity it can hold within its enclosed boundaries.

The formula to find the volume of a sphere is:

Volume of the sphere = 4/3× π ×r^3 cubic unit

Volume of the sphere       =  4/3× π ×( 18 )^3 cubic unit

Volume of the sphere       = 7776π  cubic unit

Therefore, the volume of a sphere with a radius of 18 units will be 7776π units.
