Answer 1

Answer:

The Curved Surface Area (CSA) of the frustum of a cone is: = pi * l(R + r) where the (r) stands for = radius of the smaller circle and (R) stands for = radius of the bigger circle and the (l) = slant height of the frustum.

Answer 2

Answer:

The curved surface area of frustum of a cone is given by;

CSA = πl(R – r)

Where r is the radius of upper circle or small circle of frustum and R is the radius large circle or base and l is the slant height.
