Question

The volume, V, of the right circular cone with radius r.

and height h, shown below, can be found using the
formula V= { ar?h. A cone-shaped paper cup has a
volume of 142 cubic centimeters and a height of
8.5 centimeters. What is the radius, to the nearest
centimeter, of the paper cup?

Answer 1

radius^2 = 3 * Volume / (PI * height)

radius^2 = 3 * (142 cc / 3.14159265 * 8.5)

radius^2 = 3 * (142 cc / 26.703537525 )

radius^2 = 15.9529425493

radius = 4.0 cm
