Question

An ice cream waffle cone can be modeled by a right circular cone with a base diameter of 8.2 centimeters and a volume of 68.42 cubic centimeters. What is the number of centimeters in the height of the waffle cone? Round to the nearest hundreth

Answer 1

3.9

Explanation:

Formula of Cone volume =
`\pi r^(2) (h)/(3)`

Radius = 8.2/2 = 4.1

`68.42=\pi 4.1^(2) (h)/(3)`

`\pi 4.1^(2) (h)/(3)=17.6h`

Divides by both sides by 17.6

68.42/17.6 = 17.6h/17.6

3.8875 = h
