a. 240pi cm^3
b. 1200pi cm^3
c. 1440pi cm^3

Best ResponseYou've already chosen the best response.0\[\huge B \times h\] B means the area of the base.. in other words out formula is like: \[\huge (\pi r^2) \times h\]

Best ResponseYou've already chosen the best response.0@Legendary maybe you have got the answer right  but if you look at the answers they have left pi in the answer have you maybe multiplied pi * r^2 * h (that would give 4000 something...)

Best ResponseYou've already chosen the best response.0read my post  your answer IS correct  but the answer given has pi left as pi  not multiplied out by 3.14...

Best ResponseYou've already chosen the best response.0we are doing it in terms of pi. in other words, we will work with the radius and the height in the formula, but not the pi. r^2 = 12^2 = 144 height = 10 144 x 10 = 1,440 and we will attach pi to 1440 \[\large 1,440\pi\]
