Best ResponseYou've already chosen the best response.0You didnt include the formula, so I will use the one I know: \[V(r)=\frac{4}{3} \pi r^3\]Which can be solved by substitution: \[V(3)=\frac{4}{3} \pi (3)^3=4 \pi (3)^2=4\pi(9)=36\pi\]I'm not sure why the answer doesn't line up, but my guess would be that in the formula that is (supposed to be) given for this problem. The volume's "units" contain a \[\pi\] so the answer would just be 36.
