Circumference of Circle
a and b are the two bases
The circumference of a circle is the distance around its outer edge or boundary. It is given by the formula:
C = 2πr
where C is the circumference, π (pi) is a mathematical constant approximately equal to 3.14159, and r is the radius of the circle (the distance from the center of the circle to any point on its edge).
The formula can also be written as:
C = πd
where d is the diameter of the circle (the distance across the circle passing through its center). The relationship between the radius and diameter is:
d = 2r
Therefore, if you know the value of the radius or the diameter, you can easily calculate the circumference of the circle using the above formulas.
