The circumference of a circle is the total distance around its outer edge. Imagine walking around a circular pond – the distance you cover is the circumference....
The Formula for Circumference
The formula to calculate the circumference of a circle is simple:
Circumference = 2 * π * radius
Where:
- π (pi) is a mathematical constant approximately equal to 3.14159.
- radius is the distance from the center of the circle to any point on its edge.
Applying the Formula to the Pond
In this scenario, you have a pond with a diameter of 60 feet. The radius is half the diameter, so:
radius = diameter / 2 = 60 feet / 2 = 30 feet
Now, we can plug the radius into the circumference formula:
Circumference = 2 * π * 30 feet = 60 * π feet ≈ 188.49 feet
Conclusion
Therefore, if you walked around the perfectly circular pond with a diameter of 60 feet, you would have walked approximately 188.49 feet.
