Circumference formula
The circumference of a circle is the distance around the edge or boundary of the circle
The circumference of a circle is the distance around the edge or boundary of the circle. The formula to calculate the circumference of a circle is:
C = 2πr
Where:
C represents the circumference of the circle.
π (pi) is a mathematical constant approximately equal to 3.14159. It is often rounded to 3.14.
r represents the radius of the circle.
To use this formula, you need to know the radius of the circle. The radius is the distance from the center of the circle to any point on its boundary. Once you have the radius, you can substitute it into the formula to find the circumference.
Let’s say you have a circle with a radius of 5 units. You can calculate the circumference using the formula:
C = 2πr
C = 2 * 3.14 * 5
C = 31.4 units
So, the circumference of a circle with a radius of 5 units is 31.4 units.
It is important to note that if you are given the diameter of the circle instead of the radius, you need to divide the diameter by 2 to get the radius before using the formula. The diameter is the distance across the circle passing through its center.
