The area of the lateral surface of a truncated cone with the radius of the lower base R = 23, with the radius of the upper base r = 2000, and the generative L = 2000 equal to 12710509

What needs to be found:
Radius R: Radius r: Forming L:

truncated cone

A truncated cone is a part of a cone located between its base and a secant plane parallel to the base.
The formula of the area of the lateral surface of the cone Formula for the area of the lateral surface of a truncated cone truncated cone where R is the radius of the lower base,r is the radius of the upper base, L is the length of the generatrix.

Solution:
S = πL·(R+r)
= π·2000·(23+2000)
= π·2000·2023
= 4046000·π
=
12710509
