A dish, in the shape of a frustum of a cone, has a height of 6 cm. Its top and its bottom have radii of 24 cm and 16 cm respectively. Find its curved surface area (in `cm^2`).

Text Solution

Verified by Experts

Lateral surface area=>`pi(R+r)sqrt((R-r)^2+h^2)`
substituting values we get=>`22/7xx40xx10=400pi(cm)^2`
