    What does the picture say? \(d=6h=15...\) Is there something after that? Or is that just \(15[cm]\)?

    Anyway, the volume for a cylinder is the area of the circle times the height, so\[V=\pi\ r^2\ h\]

    Okay, the volume is 441.78

    Now, the volume of the water is \(\frac{1}{3}\) that.

    The result should be in terms of pi

    You have two answer choices that are exactly the same. I'm pretty sure they're supposed to be all different.

    Alright! Got it now, I got 45ð cm3. Thank you both! =)

    I agree! I got the cylinder's volume to be \(140.625\pi\) and \(\frac{1}{3}\) of that to be \(46.875\pi\)
