Jim's company makes solid balls out of scrap metal for various industrial uses. For one project, he must make steel balls that have a radius of 3in. If steel costs $0.25 per in3, how much will the steel cost to make one ball?

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.
