What is a Cylinder ?

A cylinder is a three-dimensional geometric shape characterized by its two parallel circular bases and a curved surface connecting the bases. It can be thought of as a can or a pipe.

The formula for calculating the Surface Area (SA) of a cylinder is given by:

V = 2 x π x r x (r+h)

where:

  • V is the volume of the cylinder
  • π (pi) is a mathematical constant approximately equal to 3.14159265359
  • r is the radius of the base of the cylinder.
  • h is the height of the cylinder, measured perpendicular to the base.

To use the formula, simply plug in the values for the radius and height of the cylinder, and then calculate the result. Remember to use consistent units for your measurements.
