Question

formula to find curved surface area of frustum of cone​

Answer 1

Step-by-step explanation:

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 formula of Curved surface area of frustum is $“π(r_{1} + r_{2}) l”$
