what is the area of one end of the cylinder? (leave pi in the answer...)
\[\huge B \times h\]
B means the area of the base.. in other words out formula is like:
\[\huge (\pi r^2) \times h\]
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...)

i got 4,523
i dont get it
read my post - your answer IS correct - but the answer given has pi left as pi - not multiplied out by 3.14...
okay so what do i do
we 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
