Half circumference of a circle
WebPi ( π) π. Draw a circle with a diameter (all the way across the circle) of 1. Then the circumference (all the way around the circle) is 3.14159265... a number known as Pi. Pi (pronounced like "pie") is often written using the greek symbol π. The definition of π is: The Circumference. divided by the Diameter. of a Circle. WebThe circumference is equal to 2 times 5 times the radius. So it's going to be equal to 2 times pi times the radius, times 3 meters, which is equal to 6 meters times pi or 6 pi meters. 6 pi meters. Now I could multiply this out. Remember pi is just a number. Pi is 3.14159 going on and on and on.
