Question

Ow do you fond the surface area of a cone

Answer 1

To find the surface area of a cone you can use the formula
A = $\pi$r(r + $\sqrt{h ^{2} }+r ^{2} )$
Hope I helped!

Answer 2

Since the base of a cone is a circle, we substitute 2πr2πr for pp and πr2πr2 for BB where rr is the radius of the base of the cylinder.

So, the formula for the lateral surface area of a right cone is L.S.A=πrlL.S.A=πrl , where ll is the slant height of the cone.
