Question

Ow do you fond the surface area of a cone

Answer 1

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.

Answer 2

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