Circumference of a circle
The circumference of a circle is the total length of the boundary or the distance around the circle
The circumference of a circle is the total length of the boundary or the distance around the circle. It is the longest distance that can be measured along the edges of the circle. The circumference of a circle is calculated using the formula:
C = 2πr
Where:
– C represents the circumference of the circle
– π (pi) is a constant approximately equal to 3.14159 (Although it is an irrational number, it is commonly approximated as 3.14 for simplicity)
– r denotes the radius of the circle
To find the circumference, you would need to know the radius of the circle. If the diameter of the circle (the distance across it, passing through the center) is given instead, you can find the radius by dividing the diameter by 2. Once you have the radius, you can use the formula to calculate the circumference.
For example, if the radius of a circle is 5 units, you can calculate the circumference as follows:
C = 2π(5)
C = 10π
C ≈ 10 * 3.14
C ≈ 31.4 units
Therefore, the circumference of a circle with a radius of 5 units is approximately 31.4 units.
