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
