To find the volume of the sculpture, we first need to find the volume of the larger hemisphere and then subtract the volume of the smaller hemisphere.
Volume of larger hemisphere:
V1 = (2/3) * pi * 20^3
V1 = (2/3) * 3.14 * 8000
V1 = 16747.467
Volume of smaller hemisphere:
V2 = (2/3) * pi * 15^3
V2 = (2/3) * 3.14 * 3375
V2 = 7065.0
Volume of sculpture = V1 - V2
Volume of sculpture = 16747 - 7065
Volume of sculpture = 9682
Therefore, the volume of Kairay's sculpture is 9,682 inches cubed.
Question 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) Responses 16,747 in.3 16,747 inches cubed 7,065 in.3 7,065 inches cubed 9,682 in.3 9,682 inches cubed 19,363 in.3
