Question
If you have two similar objects that have a scale factor of 6:11, what is the ratio of their surface areas?
Solution
The ratio of the surface areas of two similar objects is the square of the scale factor.
Step 1: Identify the scale factor. In this case, the scale factor is 6:11.
Step 2: Square each part of the scale factor.
(6)^2 : (11)^2 = 36 : 121
So, the ratio of their surface areas is 36:121.
