Circumference is how far around a circle goes, and this formula helps you find that distance based on how much of the circle you're looking at.
Imagine you have a pizza. A full pizza is 360°, like a complete circle. If you take just a slice, say a quarter of the pizza, that’s 90°. Now, if you know how far around the whole pizza is, its circumference, you can figure out how long your slice's crust is by using this idea:
Circumference = Distance / Angle × 360°.
Like a Pizza Slice
Think of it like sharing a pizza with friends. If the whole pizza has a crust length of, say, 24 inches, and you only have one slice that’s 90°, you can find out how long your slice's crust is by comparing it to the full pizza.
You take the total crust length (24 inches) and divide it by the full angle (360°), then multiply by the angle of your slice (90°). That gives you 24 / 360 × 90 = 6, so your slice’s crust is 6 inches long.
It's like cutting a pizza and knowing how much crust each person gets just by looking at their slice! Circumference is how far around a circle goes, and this formula helps you find that distance based on how much of the circle you're looking at.

Examples
- A wheel makes one full turn, it travels a distance equal to its circumference.
- If you walk around a circular track once, the total path is its circumference.
- A pizza cut into 8 slices has an angle of 45° for each slice.
