Question

write the formula to find the total surface area of a frustum of cone​

Answer 1

Answer:

The total surface area of the frustum of the cone = π (l) (R+r) +πR2 +πr2

The slant height (l) shall be = √[H2 +(R-r)2]

Answer 2

Hey mate ur answer is

1. TSA of frustum of cone = π * (r12 + r22 + (r1 + r2) * s) = π * [ r12 + r22 + (r1+ r2) * √((r1 - r2)2 + h2) ]

hope it help u.....✌✌
