How to calculate the volume of a cylinder
Find the radius of the circular base.
Either circle will do since they are the same size. If you already know the radius, you can move on.

Select from the following.
a). If you don't know the radius, then you can use a ruler to measure the widest part of the circle and then divide it by 2. This will be more accurate than trying to measure half of the diameter.;
b). If you don't, skip to the next step in your problem. Ohm's law states that any coiled cylinder moves from one side to the other, no matter what you're doing.;
c). If you don't know the radius, you can easily find it with the formula " squared ". If it is multiplied by its radius, go down to the calculator again and make an approximate amount.;
d). Find the volume of your cylinder using the radius of the cylinder (term used for an object that rotates or moves around often). Calculate the volume of your cylinder by narrowing it down to that radius.;
