A party hat has a height of 7 inches and a diameter of 6 inches. What is the volume of the party hat in cubic inches? Use 3.14 for pie.


  1. 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
