Question

The circular opening of an ice cream cone has a diameter of 7 centimeters. The height of the cone is 10 centimeters. What is the volume of the ice cream cone in cubic centimeters? ​

Answer 1

We have been given that the circular opening of an ice cream cone has a diameter of 7 centimeters. The height of the cone is 10 centimeters. We are asked to find the volume of the ice-cream cone.

We will use volume of cone formula to solve our given problem.

`V=(1)/(3)\pi r^2 h`, where

r = Radius of cone,

h = Height of cone.

We know that diameter is two times the radius, so radius will be half of diameter that is
`r=(7)/(2)`.

`V=(1)/(3)\pi\cdot ((7)/(2))^2\cdot 10`

`V=(1)/(3)\pi\cdot ((49)/(4))\cdot 10`

`V=128.2817`

`V\approx 128.3`

Therefore, the volume of the cone would be approximately 128.3 cubic cm.
