Question

What numbers do you need to determine the surface area of a right cone? ANSWERS: The radius of the base, r, and the altitude h. The altitude h and the slant height s. The radius of the base, r, and the slant height s. You must have all three numbers r, s, and h.

Answer 1

The radius of the base, r, and the slant height s.

Explanation:

pf

Answer 2

The Radius of the base, r, and the altitude h

Explanation:

Surface area of a right cone

`a=\pi r\sqrt{h^(2)+r^(2) }`

R= Radius

H=Radius
