1
Main Idea/Vocabulary similar solids Find dimensions, surface area, and volume of similar solids.

2
Example 1 Find Missing Linear Measures These cones are similar. What is the radius of Cone A to the nearest tenth? Since the two cones are similar, the ratios of their corresponding linear measures are proportional. Words Variable Equation

3
Example 1 Find Missing Linear Measures Write the proportion. Divide each side by 12. Answer: The radius of cone A is about 4.7 centimeters. Find the cross products. Multiply. Simplify.
