Online calculator which will help you to find the lateral surface area of a truncated cone to calculate the area of a truncated cone is the lower radius (r1), (r2) and the bases forming (l).
A truncated cone – shape resulting from the holding section in the cone, the cross section is parallel to the base of the cone.
The area of a truncated cone can be recognized by the formula S = pH (r12 + (r1 + r2) x l + r22).
