Are you talking about a cylinder?
If so,
V = pi*r^2*h
314 = 3.14 r^2 * 25
100/25 = r^2
r = sqrt 4 = 2 feet
If so,
V = pi*r^2*h
314 = 3.14 r^2 * 25
100/25 = r^2
r = sqrt 4 = 2 feet

Just set up you equation and plug in what numbers you know.
Volume = pi x r^2 x height
314 = 3.14 x r^2 x 25
multiply on the same side of the =
314 = 78.5 x r^2
now, divide both sides by 78.5 to get the variable by itself
Finally, take this small, easy to work with number and find its square root!
Hope this helps!
