How do you find the circumference of a circle?

Answer: The circumference of a circle can be found using the following formula:

Circumference = 2πr

Where:

  • Circumference is the total distance around the circle.
  • π (pi) is a mathematical constant approximately equal to 3.14159.
  • r is the radius of the circle, which is the distance from the center of the circle to any point on the edge.

To find the circumference, you need to know the value of the radius. If you don’t have the radius, but you have the diameter (the distance across the circle through the center), you can use the formula:

Circumference = πd

Where:

  • d is the diameter of the circle.

Once you have the value of the radius or diameter, you can plug it into the formula and calculate the circumference.

For example, let’s say you have a circle with a radius of 4 units. Using the formula, the circumference would be:

Circumference = 2π(4) = 8π units

If you have a circle with a diameter of 10 units, you can calculate the circumference as:

Circumference = π(10) = 10π units

Remember to use the appropriate units based on the measurements provided.
