Answer:
65.94 in³
Step-by-step explanation:
First, we need to determine to the shape, a party hat is a cone.
The volume formula that use to calculate the cone is 1/3hπr².
Notice: h is for height and r is for radius
Using this formula, we can easily set up the equation below:
1/3 · 7 · 3.14 · (6/2)² = 65.94 (cubic inches)
You must halved the diameter first (in this case, 6) and then square it.
So: The answer of this question is 65.94 in³
