Cone lateral area calculator
Formula for the lateral area of a cone:
Assume that the radius of the base of the cone is r, the height is h, and the generatrix length is l (l^=r^+h^).
The side view of the cone is a sector with a radius of l and an arc length of 2πr.
∴The lateral area of the cone = (1/2)(2πr)l=πrl
