What is the volume of a sphere with a radius of 18 units? A. 7776 units

B. 1296 units

C. 5832units

D. 1944 units 3

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.
