Find the ratio of the volumes of (a) two similar solid cylinders of circumferences 10cm and 8 cm; (b) two similar solid cones of heights 9cm and...

If you have
two similar figures then the ratio of corresponding lengths is a constant called the scale
factor. If the scale factor between two similar figures is a:b, then the ratio of any
corresponding lengths is a:b. The ratio of any corresponding areas is `a^2:b^2` and the ratio
of...
