Question

How much water can be held by a cylindrical tank with a radius of 12 feet and a height of 30 feet?

Answer 1

To answer this, we need to use the equation for the volume of a cylinder:
$V = \pi r^{2}h$
Where:
'V' : Volume
'r' : radius
'h' : height

Now we plug in our values and solve:
$V = \pi (12)^{2}(30)$
$V = \pi (144)(30)$
V = 13571.68 cubic feet

∴Despite not being exactly what we got, the answer must be 'B'. It is the closest value to our solution without going over. 

Hope this helps!
