Best Answer

The surface area of a cone of height 'h' is (Pi) r2 + (Pi) r l, where r - radius of the circle part (base) of the cone, l - slant height of the cone found by the Pythagoras formula as l2 = h2 + r2 and Pi = 3.14 approximately.

It depends on whether you want the volume, angle at the apex, height, radius etc. And in each case, the formula will depend on what information is available.
