It isn't 3.14 x r squared, that is the circumference of a circle, which I know has a part in finding the volume. I'm wanting the volume not the suface area.

Volume of a prism or cylinder = Area of the Base * Height
In the case of a cylinder, the base is a circle
V=pi*r^2*h

The formula for volume of a cylinder is pi x r x r x h which is just the area of a circle (pi x r x r) times the height of the cylinder. The answer will be in cubed (third power) units

When you are using pie x r square, it gives the air enclosed in a circle.
If you multiply the height or length (Both mean same) of the cylinder, you will get the amount of air enclosed in a cylinder. That is nothing but the Volume of the cylinder.
Therefore Volume of Cylinder is pie r square h
Where 'h' is the height of the cylinder

it is not circumference it is area,so the volume will be 3.14 into (r squared) into the height of the cylinder

if it is a solid cylinder than volume would be
pie x raduis^2 x lenght of cylinder
if it is a hollow than volume would be
pie(outer ID^2 - Inner ID^2) x length
if it is a hollow with base than
(pie x outer id^2 x thickness of the base) + ( pie x(outer id^2 - inner id ^2) x lenght after base thickness.
all above methods are to find out the the material volume but if you want to know the fill volume than
pie x inner id^2 x lenght after bas thick ness
good luck

pi x radius squared (= area of the cross-section) x length of the cilinder.
by the way, the circumference of a circle = 2 x pi x radius = pi x diameter of circle

pi x r^2 = area of one side of the cylinder.
Then multiply that times the height of the cylinder.

Multiply the surface area time the height of the cylinder. That'll do.

If 'r' is the radius and 'h' is the height of cylinder then you can find the volume of cylinder by the formula - 3.14x r squered x h
