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

Answer:6 weeks
Step-by-step explanation: 5, 10, 20, 40, 80, 160
9" = the diameter
4.5" = the radius
area of a circle = π * r^2
area of pie = 4.5^2 * π
8-3 = 5 so 5/8 remaining
5/8 * 4.5^2 *π
this is equal to 39.7 which rounds to 40"^2
