The area of a circular base of the larger cylinder is 81π. The area of a circular base of the smaller cylinder is 9π.



Make a conjecture about the similar solids. How is the scale factor and the ratio of the surface areas related? Check all that apply.

The dimensions of the larger cylinder are 3 times the dimensions of the smaller cylinder.
The surface area of the larger cylinder is 32, or 9, times the surface area of the smaller cylinder.
If proportional dimensional changes are made to a solid figure, then the surface area will change by the square of the scale factor of similar solids.
