Main Question:What is Circumference/Diameter and how do I find it?I am currently working with my mom and I have no idea what it is. it is on a major project and I need help working on it, and I have already asked my Math teacher for help. He did not really show much help other than what I already know. I have provided an image for you to better understand my problem... ​

circumference is actually a closed boundary of a curved geometric figure like circle.it can be calculated by applying the formula C = π * d ( d= diameter)or C = 2πr ( r= radius)you can use any one to find out the circumference of the circle.But from your attached document,it is clear that circumference is given, sorry, I don't understand for what you are looking for?diameter goes straight through the center of a circle and touches the boundaries of the circle in both sides.Diameter is always double of radius, D = 2r ( r= radius)or you can find radius by dividing it by 2, r = D/2I hope it will serve your purpose.
