Question

TSA of frustum of cone​

Answer 1

Total Surface Area of frustum =

πr² + πR² + π(R-r) l

Answer 2

The surface area and the volume of the frustum of a cone can be calculated using standard formulae. CSA of the frustum of a cone = πl( r1 + r2). where r1 = radius of the larger circular face of the frustum, r2 = radius of the smaller circular face of the frustum, and l = slant height of the frustum.
