The surface area is a function of the height (or slant height) and the radius of the base. So, the slant height is a function of the surface area and the base-radius. Since the latter is unknown, the slant height cannot be calculated.
Curved surface area = pi*radius*slant length = 792 square cm radius = 792 divide by (pi*slant length)
A slant height of 20 and base circle radius (r) of 20 gives slant length (s) = 28.284 equation for cone surface area : (pi * r * s) + (pi * r2) = 1777.136 + 1256.637 = 3033.773 units2

A right cone with a radius of 4 and a slant height of 13 has a total surface area of about 213.63 units2
The surface area of a right cone with a radius of 8 and a slant height of 15 is: 377 units squared.
These dimensions are not possible for a right cone. The radius must be less than the slant height. If we reverse the dimensions (radius 6, slant height 9) the total surface area will be about 282.74 units2
A right cone with a slant height of 6 and a radius of 7 has a total surface area of about 245.04 square units.
Surface Area = Pi*radius(radius + slant height)
The lateral surface area of a right circular cone with a radius of 12cm and a slant height of 20cm is approximately 754cm2
The surface area is a function of the height (or slant height) and the radius of the base. So, the slant height is a function of the surface area and the base-radius. Since the latter is unknown, the slant height cannot be calculated.

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.
A cone with a slant height of 22cm and radius of 7cm has a total surface area of about 637.74cm2
A right circular cone with 8 height and 6 radius has a slant height of 10.
Slant height is 7.81 inches.
