Answer 1

To calculate the volume of the sculpture, we need to find the volume of the larger hemisphere and subtract the volume of the smaller hemisphere.

The volume of a hemisphere is given by the formula V = (2/3)πr^3.

For the larger hemisphere with a radius of 20 inches:
V1 = (2/3)(3.14)(20^3) = 33523.2 inches cubed (rounded to the nearest whole number)

For the smaller hemisphere with a radius of 15 inches:
V2 = (2/3)(3.14)(15^3) = 7065 inches cubed (rounded to the nearest whole number)

Therefore, the volume of the sculpture is V1 - V2 = 33523.2 - 7065 = 26458.2 inches cubed (rounded to the nearest whole number)

The correct answer is: 26,458 in.3.
