📏 How to Calculate the Circumference of a Circle?

The circumference of a circle is the total distance around its edge. You can calculate it using one of the two formulas:

1️⃣ Using Radius ($r$)

$$C=2\pi r$$

• If you know the radius, multiply by 2π (approx. 3.1416) to get the circumference.

2️⃣ Using Diameter ($d$)

$$C=\pi d$$

• If you know the diameter, simply multiply by π to get the circumference.
