In this case, we'll have to carry out several steps to find the solution.
Step 01:
Data
base = 5.25 inches
height = 8.40 inches
cone volume = ?
Step 02:
volume of a cone formula
V = 1/3 π r² H
base = diameter
r = diameter / 2
r = 5.25 inches / 2
V = 60.61 inches ³
The answer is:
The volume of the cone is 60.61 inches³
