Acylinder has a radius of 5 cm and a height of 4cm find the volume

The answer should be around 314.159. The formula is v=pi*r2*h. Plug in the numbers and its v=pi*25*4. That is 25*4 which is 100. Then *pi and it should be it.

It should be 314

So there is a total of 14 marbles and when Bill takes one red out it becomes 13 marbles. So the probability of Bill drawing a yellow marble is 2 yellow marbles (because there are 2 yellow) out of 13. So the answer is the probability is 2/13 of drawing yellow!
