Question
A party hat has a volume of 75
cubic inches. If the radius is 5 inches, what is the height of the party hat?
- 3 in
- 15 in
- 6 in
- 9 in
Hint:
Volume of Cone =
Solve above equation for h , rest of values are given in the Question .
The correct answer is: 9 in
Given a Cone with volume of 75
cubic inches
radius = 5 inches And height = ?
Volume of Cone = 
putting the values and solving for h we get
135 5 h = 75in3
h = 9 in
So , the height of the cone is 9 inches .
