How do you find the circumference of a circle?
Answer:
The circumference of a circle can be calculated using the formula:
Circumference = 2 × π × r
In this formula:
- C represents the circumference of the circle,
- π is a constant approximately equal to 3.14159,
- r is the radius of the circle (the distance from the center of the circle to any point on its edge).
To find the circumference of a circle, you multiply 2 by π (pi), and then multiply that result by the radius of the circle. This formula works because the circumference of a circle is the distance around the circle. It’s worth noting that if you know the diameter (d) of the circle instead of the radius, you can simply use the formula C = π × d to find the circumference. Circumference is an essential measurement when dealing with circles in mathematics and real-world applications.
