Let's pretend the radius of the cylinder's circular base is 4. You need to square the radius of the base first. In this case, we will do 4x4 which is 16. (4x4=radiusxradius). Next, you will do 16 (radius times radius) multiplied by pi. In our example, the we will do 16 times pi which is 50.26548246. Now, let's pretend the height of the cylinder is 7. We will multiply 50.26548246 by 7 and get 351.8583772. This is the volume of our cylinder.

. Find the volume of a cylinder with radius 5 cm and height 7 cm.
Find the cross-sectional area of the cylinder (pi x the radius2), the multiply that by the height of the cylinder
Volume = pi*radius2*height measured in cubic units
Volume is 90.4779 mm3
In order to find the volume of the cylinder more information is required as to the actual dimensions of the cylinder. Volume is calculated by knowing the radius and height of the cylinder.
