An icicle is in the shape of an inverted cone with a diameter of 12 millimeters and a height of 100 millimeters. How much frozen water is in the icicle? Round to the nearest hundredth.Cone

The volume of a cone is V = (1/3)πr²h. The diameter is 12 mm, so the radius is 6 mm; using the height of 100 mm gives V = (1/3)π(6²)(100) = 1,200π ≈ 3,769.91 mm³. The icicle contains about 3,769.91 mm³ of frozen water, choice C.
