do you mean that the height and the radius are proportionally larger in the bigger cone?

im not sure its the second one in this picture.

surface area = 96
so what is the radius?
OpenStudy (anonymous):
what is the formula for SA of a cone?
what is the formula for Volume of cone?
OpenStudy (anonymous):
R=2.76395
OpenStudy (anonymous):
Cone (surface) pi * radius * side
Cone (1/3) * pi * radius2 * height
