Question

what is the formula of CSA of frustum of cone​

Answer 1

Answer:

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:

C.SA of Frustum of Cone is πl(R+r)

Where π→constant ,l→ slant height R→ Radius of Bigger Circle and r → radius of Smaller Circle.
