    This is a proportion problem; you need to know how to set up a proportion to estimate the radius of the larger cone. You also need to know how to compute the surface area of a cone. Where are you stuck?

    I'll give you a hint: the surface area of a cone is\[SA=\pi r^2+\pi rl,\]where|dw:1346792025872:dw|

    That's about half of the problem right there, and what do you mean with "everything"?
