Best ResponseYou've already chosen the best response.1ya your post jsut showed up

Best ResponseYou've already chosen the best response.1So let's plug in the values from your problem: \[v = 4/3 * \pi * 10^3\] \[v = 4/3 * \pi * 1,000\] When you plug this all in (you can do it on a calculator), you'll find that 4/3 = 1.3. so: \[v = 1.3 * 3.14 * 1,000\] And then you'll get your answer. :)

Best ResponseYou've already chosen the best response.1Sorry; my mistake. You should have rounded 1.3 and input 1.4 (since 1.3333333... is irrational) and you would have gotten 4,187 :)
