Best ResponseYou've already chosen the best response.1hints: 7^2 = 7*7 8^2 = 8*8 9^2 = 9*9 10^2 = 10*10 etc etc In general x^2 = x*x

Best ResponseYou've already chosen the best response.1So you have computed \[\large \frac{1}{3}*5^2*6\] You found that \[\large \frac{1}{3}*5^2*6=50\]

Best ResponseYou've already chosen the best response.1Now just place the 'pi' back in \[\Large \frac{1}{3}\pi*5^2*6=50\pi\]

Best ResponseYou've already chosen the best response.0sooo 50 *3.14 = 157?

Best ResponseYou've already chosen the best response.1when they say exact volume they mean in terms of pi. They even say "in terms of π" in the instructions. That means you do NOT replace pi with 3.14 and multiply. You just leave the pi alone. So it's simply \(\Large 50\pi\)

Best ResponseYou've already chosen the best response.1157 would work for the approximate volume though
