How to circumference using Pi

     Finding the circumference of a circle with a 3 foot diameter is pretty easy if you know how to do the math. First you must find the radius of the circle then you multiply it with the diameter. It was Pi day last week and everything was about Pi. My math teacher even made us go outside and do an activity on how to find the circumference of Pi. He told step for step and then solved it. Then we went back inside and did more math stuff like problems. Everybody in my class knew what Pi was. Pi equals 3.14.
