How do you find scale factor of similar objects?
Assuming you are already sure that the two objects are, indeed, similar: You measure corresponding lengths of the two objects, and divide.You measure the lengths of a pair of corresponding sides. The scale factor is the ratio of the two measures.
How do you find the ratio of an object?
You cannot. You can only find a ratio of two or more objects. Then, it can be the ratio of their size, volume, mass, monetary value, temperature - or any other characteristic that can be measured.
How do you find the ratio of two similar cones that have heights of 9cm and 4cm?
The ratio of their heights is 9:4
How do you find the volume of a similar prism with only the scale factor and volume of the other prism?
The ratio of the volumes of similar solids is (the ratio of their linear dimensions)3 .
How do you find the ratio of two similar 3 dimensional figures when only given the surface area?
Notice the exponents in these two statements.Those little tiny numbers tell the whole big story:(the ratio of the surface areas of similar figures) = (the ratio of their linear dimensions)2(the ratio of the volumes of similar solids) = (the ratio of their linear dimensions)3
