Question

What is the surface area of this object? I think its a cone.

Answer 1

If it is a cone then its curved surface area = \(\large{\pi*r*(r + l)}\)

where, l = slant height of the cone = \(\large{\sqrt{r^2 + h^2}}\)

Answer 2

Sorry this was the total surface area.

Curved surface area of cone = \(\large{\pi*r*l}\)
