<PRE><B>Question 110277</B>
A cylinder has a radius of 5 in. If the volume of the cylinder is 250 in.3. What is the height of the cylinder? (Hint: The volume of a cylinder is give by v = r2h.) 
----------------
Formula: Volume = Bh, where B is the base of the cylinder = (pi)r^2 and h is height.
----------------
Your Problem:
Substitute to solve for the height
250 cu.in = (pi)(5^2) h

h = 250/(25pi) in
h = 3.1831 in
