Circumference
The circumference of a circle is the distance around the outer edge or boundary of the circle
The circumference of a circle is the distance around the outer edge or boundary of the circle. It can be calculated using the formula:
C = 2πr
Where:
– C represents the circumference of the circle
– π (pi) is a mathematical constant approximately equal to 3.14159
– r is the radius of the circle
To find the circumference, you need to know the value of the radius. The radius is the distance from the center of the circle to any point along the edge. If you have the diameter instead, which is the distance across the circle passing through the center, you can calculate the radius by dividing the diameter by 2.
Let’s say you have a circle with a radius of 5 units. Using the formula, you can calculate the circumference as follows:
C = 2π(5)
C = 10π
If you want to find the numerical value, you can approximate π as 3.14:
C ≈ 10(3.14)
C ≈ 31.4 units
So, the circumference of a circle with a radius of 5 units is approximately 31.4 units.
