\[C = 2\pi*r | \frac{ C }{ 2*\pi } = r | \frac{ 42*\pi }{ 2*\pi } = r \]

@Photon336

OpenStudy (photon336):

how did you get 6.68

OpenStudy (photon336):

the circumference is 42pi. in your formula you forgot to put pi. so the radius is going to be 21

OpenStudy (tylermckinney16):

So thats the answer?? @Photon336

OpenStudy (photon336):

so your radius is 21
