Best ResponseYou've already chosen the best response.1when you find the area using \[ \pi r^2\] leave pi in. do not use 3.14 you get \[ 36 \pi\]

Best ResponseYou've already chosen the best response.1V= 1/3 pi r^2 h if you leave the pi to one side: \[ \pi (\frac{1}{3} 36 \cdot h )\] just figure out the stuff in the parens

Best ResponseYou've already chosen the best response.1the answer is \[ 240 \cdot \pi \] 240 times pi if you replace pi with 3.14159... you get 753. with lots of decimals people just write it 240 pi and if someone wants the exact number, they can multiply it out themselves.
