formula of a cone

Answer 1

The formula for the volume of a cone is:

V = 1/3 πr²h

where V is the volume of the cone, r is the radius of the circular base of the cone, and h is the height of the cone.

The formula for the lateral surface area of a cone is:

L = πr√(r²+h²)

where L is the lateral surface area of the cone, r is the radius of the circular base of the cone, and h is the height of the cone.

The formula for the total surface area of a cone is:

A = πr(r+√(r²+h²))

where A is the total surface area of the cone, r is the radius of the circular base of the cone, and h is the height of the cone.
