Slant height of the cone = sqrt(32 + 152) = 15.297
Base surface area = π(3)2 = 9π
Curve surface area = π(3)(15.297) = 45.891π
Total surface area = 9π + 45.891π = 54.891π

What is the surface area of a right cone with a slant height of 6 and a radius of 7?
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.
What is the surface area of a right cone with a slant height of 6 and a radius of 9?
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
