use this formula C=2PIr with r being the radius and tell me what you get and if you dont get it i will explain :)

Answer 8

i already don't get it. like i have no idea what i'm doing , im so bad at math

Answer 9

C=2PIr C=2(3.146)(10.91) multiply 3.146 by to then multiply by 10.91 and tell me what you get
