Similar solids and linear scale factor

Small and large similar cylinder with matching radius and height labels, arrows showing how length, surface area, and volume scale, and a cone frustum formed by removing a small cone from a larger cone Similar 3D shapes have the same shape but different sizes. Corresponding lengths are measurements in the same position, such as radius with radius or height with height.
