A party hat has a diameter of 18 centimeters and a height of 25 centimeters. What is the volume of air it can occupy?

Assuming the party hat is a cone shape,

 

volume of cone = (1/3) * (π * radius2 ) * (height)

volume of cone = (1/3) * (π * [18/2]2  ) * (25)

volume of cone = (1/3) * π * 81 * 25

volume of cone = 675π   cubic cm,

                            which is  ≈  2120.575 cubic cm
