Question

Kim works at an ice-cream store. She wants to calculate how much ice-cream one cone can hold. If the cone is 6 inches tall and the circular opening at the top is 2.5 inches across, how much can the cone hold? Round to the nearest tenth at the end.

Answer 1

The cone holds 9.8 cubic inches ice cream

Explanation:

Height of cone = 6 inches

The circular opening at the top is 2.5 inches across

Diameter of cone = 2.5 inches

Radius of cone =
`(2.5)/(2)=1.25`

Volume of cone =
`(1)/(3) \pi r^2 h`

Volume of cone =
`(1)/(3) * 3.14 * 1.25^2 * 6`

Volume of cone =
`9.8125 in^3`

Hence the cone holds 9.8 cubic inches ice cream.
