Answer:

.

Step-by-step explanation:

The cone height formula using slant height is √l2 - r2, where l is the slant height and r is the radius of the cone. This formula is derived using the Pythagoras theorem.

Answer:

The surface area of an ice cream cone is 282.74 sq. cm.

Step-by-step explanation:

[tex]A = (r+\sqrt{h^{2}+r^{2}}) \\\\A = (5+\sqrt{(12)^{2}+(5)^{2}} ) \\\\A = 282.74[/tex]
