The formula for the lateral area (that is, the surface area of the sides, but not of the bottom) A of a cone with radius r and slant-height s is given by:

. . . . .

So plug in for A and 12 in for r. Solve for the value of s. :wink:

If you get stuck, please reply showing all of your steps so far. Thank you! :D
