Circle Circumference
The circumference of a circle is the distance around its outer boundary
The circumference of a circle is the distance around its outer boundary. It is calculated using 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.
To find the circumference of a circle, you need to know the value of the radius. The radius is the distance from the center of the circle to any point on its edge.
Here’s a step-by-step guide on how to find the circumference:
1. Determine the radius (r) of the circle. Let’s assume the radius is 5 units.
2. Use the formula C = 2πr. Plug in the value of the radius:
C = 2π(5)
3. Calculate the circumference using the formula:
C = 2 × 3.14159 × 5
4. Simplify the expression:
C ≈ 31.4159 units
Therefore, the circumference of a circle with a radius of 5 units is approximately 31.4159 units.
