Why do you need to FIND the slant height if you have the [lateral height and] slant height?

Assuming it is a right cone, use Pythagoras - slant height = hypotenuse, other two sides = radius of base, and height.

the slant height of a right circular cone is the distance from any point on the circle to the apex of the cone . The slant height of a cone is given by the formula ,√r2+h2 where r is the radius of the circle and h is the height from the center of the circle to the apex of the cone.

Slant height is 7.81 inches.

Assuming it is a right cone, use Pythagoras - slant height = hypotenuse, other two sides = radius of base, and height.

The height would be The square root of the square of the slant surface length minus the square of the radius of the cone at the base.

When you make a cone, you fold the cone along its slant height and thus you get the cone which is curved. So when you need to find the curved surface area (Which excludes the base) you need to use the same slant height that you folded the paper along which gave you the cone. Check out the links attached. It has some illustrations which will help.

A right circular cone with 8 height and 6 radius has a slant height of 10.

Uisng the lateral area and tha radius, you should be able to find the height of the cone. Using the height and radius as the legs of a right triangle, use the Pythagorean Theorem. The hypotenuse is the slant height.

Use Pythagoras' theorem
