+# Name: volumeofcylinder()
+
+## Examples:
+println(volumeofcylinder(5,10));
+
+## Description:
+This function will find the volume of a cylinder. A cylinder is a solid geometric figure with straight parallel sides and a circular or oval cross section. When finding the volume, the amount of space that a substance or object occupies, or that is enclosed within a container is being found. 
+
+## Syntax:
+volumeofcylinder(radius,height)
+
+##Parameters: 
+r     float: radius of the cylinder
+
+h     float: height of the cylinder
+
+##Returns:
+float

+## Description:
+This function uses the equation vf=vo+at to find the final velocity given the other parameters. Velocity is is a physical vector quantity; both magnitude and direction are needed to define it. The final velocity is the velocity at the ending time or position.
