# How do you find a circumumference of a circle?? I’m confused 😭😭😭?

don’t worry you’ll get the hang of it eventually! there are 3 key elements of a circle you have to remember: circumference=the perimeter diameter= the length across the middle radius= the length from the middle to the edge when working with circles, there is a special number called pi (π). If you’re using a calculator there is a button that represents pi (shift + x10). if you’re not using a calculator then you can represent pi as 3.14 now to find the circumference, there’s a formula you need to use. you can use: pi x diameter or 2 x pi x radius hope this helps!
