Answer:

Step-by-step explanation:
Given:
radius of cone = 3 inch
Total area of cone = 
Find the volume of the cone?
We know the area of cone =
-------(1)
Where r = radius
Ans s = side of the cone
Put the area value in equation 1
-------(1)


Put r value in above equation.



The side s = 5 inches
We know the side of the cone formula


Put r and s value in above equation.




The volume of cone is

Put r and h value in above equation.

The Volume of the cone is
