The curved surface area of a frustum of a cone is where and r2 are the radii of the two ends of the frustum and is the vertical height.


False

We know that,


Curved surface area of frustum = πl(r1 + r2)


Where, r1 and r2 are the radii of two ends (r1 > r2)


And l = slant height and



[ In the statement, formula for calculating slant height is incorrect]
