Question

Sarah is filling a glass sphere with decorative sand. the radius of the sphere is 2 inches. which is closest to the minimum amount of sand sarah needs to completely fill the glass sphere?

Answer 1

Minimum amount of sand that Sarah needs: 33 ft^3

To solve for this, we need to find out the volume of the glass sphere which is given with a radius of 2 ft.

Volume of sphere = (4/3)(pi)(radius)^3
= (4/3)(pi)(2 ft)^3
= 32/3 pi ft^3
estimated to be = 33 ft^3
