The ratio of the lengths of corresponding parts in two similar solids is 4:1. What is the ratio of their surface areas?A.8:1B.64:1C.4:1D.16:1
Question
The ratio of the lengths of corresponding parts in two similar solids is 4:1. What is the ratio of their surface areas?A.8:1B.64:1C.4:1D.16:1
Solution
The ratio of their surface areas is found by squaring the ratio of their corresponding lengths. So, if the ratio of their lengths is 4:1, the ratio of their surface areas is (4^2):(1^2) = 16:1. Therefore, the answer is D.16:1.
