Please tell Frustum formula (curved surface area, total surface area and volume).
Answers
Answer:
Total surface area of a conical frustum: A = π * (r12 + r22 + (r1 + r2) * s) = π * [ r12 + r22 + (r1 + r2) * √((r1 - r2)2 + h2) ]
Total surface area of a conical frustum: A = π * (r12 + r22 + (r1 + r2) * s) = π * [ r12 + r22 + (r1 + r2) * √((r1 - r2)2 + h2) ]Curved Surface Area of frustum of cone: Curved Surface Area (CSA) = pi * l(R + r) where r = radius of smaller circle R = radius of bigger circle l = slant height of the frustum.

Answer:
curved surface area=πl(R+r)
total surface area=πl(r1+r2)+πr1^2+r2^2
