Question

formula of volume of frustum of cone​

Answer 1

Answer:  l = h2+(r1-r2)2 h 2 + ( r 1 - r 2 ) 2 and h is the height of the frustum. TSA of a frustum of a cone = πl(r1 + r2) + πr12 + πr22. Volume of the frustum of a cone = (1/3) πh (r12 + r22 + r1 r2)

Step-by-step explanation:   Volume of a conical frustum = V = (1/3) * π * h * (r12 + r22 + (r1 * r2)).
