First, let's find the volume of the larger hemisphere:
Volume = (4/3) * pi * (radius)^3
Volume = (4/3) * 3.14 * (20)^3
Volume = 4/3 * 3.14 * 8000
Volume = 4.1867 * 8000
Volume = 33533.6
Now, let's find the volume of the smaller hemisphere:
Volume = (4/3) * pi * (radius)^3
Volume = (4/3) * 3.14 * (15)^3
Volume = 4/3 * 3.14 * 3375
Volume = 4.1867 * 3375
Volume = 14137.5
Finally, let's subtract the volume of the smaller hemisphere from the volume of the larger hemisphere to find the volume of the sculpture:
Volume of sculpture = Volume of larger hemisphere - Volume of smaller hemisphere
Volume of sculpture = 33533.6 - 14137.5
Volume of sculpture = 19396.1
Rounding to the nearest whole number, the volume of KAIRAY's sculpture is approximately 19396 cubic inches.
KAIRAY created a school by former and hemisphere for radius of 20 inches, and then removing a hemisphere with the radius of 15 inches from it. Calculate the volume of his sculpture. Used 3.14 as the approximation for pi. Run your answer to the nearest whole number.
