Remember the formula is PiD 3.14 x Diameter = Circumference of a circle. (I don't use the radius formula. IF you have the radius, then multiply that by 2 to get the diameter) After you get the circumference, wait 10 sec to hear a joke. Have fun with Pi or 3.141592653589793238462643383279502884197169399375105820974944592307816406286208. Thank you!
This is really fun and creative though. SO find your circumference with PI!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
