Cylinder A is similar to cylinder B, and the radius of A is 3 times the radius of B. What is the ratio of: The volume of A to the volume of B?
What is the ratio of: The lateral area of A to the lateral area of B?

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
