How to Find the Base of a Cylinder?

Cylinder can be defined as curvilinear geometric shape. Surface of cylinder is created by those points which are at a fixed distance from a given line segment. The Line Segment will be called as axis of cylinder. In other words, cylinder can be defined as Geometry which is enclosed by a surface and by two planes perpendicular to the axis (line segment). Cylinder can be elliptic, parabolic, or hyperbolic type depending on its cross section. Cylinder normally looks as shown below:


Cylinder is comprised of two circles at its top and bottom. Here ‘r’ is known as radius of cylinder and ‘l’ is the height of cylinder both of them will be helpful in determining how to find the base of a cylinder? Cylinder is taken to Mean, a finite section of Right Circular Cylinder. Following formula can be used to calculate the volume of cylinder:

V = π r ² l
And surface area of cylinder will be:
A = 2 π r ² + 2 π r l = 2 π r (r + l).
Area 2 π r ² is the sum of top and bottom area that is 2 π r² = (πr²) + (πr²) and area 2 π r l is called as lateral area. There are two methods to determine the base of a cylinder.

1)     If length of cylinder is given then by using following formula we can calculate the radius as r = sqrt (V / π l). Then just double the obtained radius to find the base of cylinder.

2)     Using the formula of area, we can also calculate the Diameter (base) of cylinder.
