I'm pretty sure the anwser is \(0.00(11)\)? I'm not really sure though. Btw the brackets mean that part is repeated
To get the circumference you just multiply the diameter by pi. So if your diameter is 4, then the circumferance is 4 pi
thats actually wrong sorry :(
oh wait no its right, im so sorry. btw i really liked the way you explained it, i understand now! :)
its still wrong :(
also your anwser for the first question is wrong :(
im confused how you solved the second one
But a and b have a common factor of 2, which doenst go with "integers with no common factor other than 1"
It doenst say which brackets to use
