The perimeter of a circle is like walking around the edge of a cookie. Just like you measure the distance around the edge of a cookie, you can measure the distance around the edge of a circle, which is called the perimeter.

Here's how you can find the perimeter of a circle:

Find the radius of the circle. The radius is the distance from the center of the circle to the edge of the circle. Use the formula 2 × pi × radius to find the perimeter. Pi (π) is a special number that is always the same for all circles, about 3.14. Multiply the radius by 2 to find the diameter, which is the distance from one side of the circle to the other through the center of the circle. Multiply the diameter by pi (π) to find the perimeter. The result is the perimeter of the circle, which is a measure of the distance around the edge of the circle.
