Kairay created a sculpture by forming a hemisphere with a radius of 20 inches and then removing a hemisphere with a radius of 15 inches from it. Calculate the volume of his sculpture. Use 3.14 as an approximation for pi. Round your answer to the nearest whole number.(1 point)

ok you can go mean face while i give you answers
1= 407
2=7.78
3=381
4=2325
5=9682
my grade my be failing but i dont care cuz im makin yours better
TU! @mechanic :3
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 formula for the volume of a hemisphere is (2/3) * pi * r^3.
For the larger hemisphere with a radius of 20 inches, the volume is:
(2/3) * 3.14 * 20^3 = 33493.333 in^3
For the smaller hemisphere with a radius of 15 inches, the volume is:
(2/3) * 3.14 * 15^3 = 14130 in^3
Subtracting the volume of the smaller hemisphere from the volume of the larger hemisphere, we get:
33493.333 - 14130 = 19363.333 in^3
Rounding to the nearest whole number, the volume of the sculpture is approximately 19,363 inches cubed.
