**What is the Circumference?**The circumference is the distance around a circle or you can think about it as the perimeter of the circle

**How to Find the Circumference of Circles:**

To find the circumference of circles, first you must find the diameter or radius. The diameter of a circle is a line that goes through the center of the circle, and the radius is half of that (the distance between the center point of the circle and any point on the outside of the circle). Once you have found the diameter, you multiply by pi, or 3.14.

**Class Activity:**

Remember in class we measured the diameter of seven different circles. We then compared the diameter to the measured circumference. We found that the circumference was 3 and a little more times the diameter. This is the diameter's relationship to pi. Therefore to find circumference of a circle, simply multiply the diameter (or the radius doubled) to pi.

In my opinion the circumference of a circle is same as the perimeter that is the distance around the outer edge.

ReplyDeleteThe formula of circumference is = 2 pi r (pi's symbol)

where r = the radius of the circle

and pi = 3.14(Approx)
