Question

what is volume of frustum of cone? write its csa and tsa​

Answer 1

Answer:

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.

TSA of a frustum of a cone = πl(r1 + r2) + πr1^2 + πr2^2

Volume of the frustum of a cone = (1/3) πh (r1^2+ r2^2+ r1r2)
