2) An ice cream cone is a right circular cone. The volume of a right circular cone is 1/3 the volume of the cylinder that has the same radius and height. A small cone has radius 1 inch and height 4 inches. A large cone has double the radius and double the height, so 2 inch radius and 8 inch height. What is a good estimate for the scale factor giving the change in volume of ice cream the large cone can hold compared to the small cone?

- Small cone volume: _______
- Large cone volume: _______
- Scale factor = ______
