Answer 1

I'm doing some resubmitions trying to get my grade up, and this has me stumped

Answer 2

@satellite73 you're always a huge help. If you have the time can you check this out?

Answer 3

so what is the arc length formula?

Answer 4

s=r(theta)

Answer 5

i think

Answer 6

\[\frac{s}{r}=\frac{\pi}{3}\] because that is how you measure the angle

Answer 7

solve
\[\frac{8.1}{r}=\frac{\pi}{3}\] for \(r\)

Answer 8

wow that's it? thank you so much

Answer 9

would it be 7.73?

Answer 10

i don't know i didn't do it
it will be \[r=\frac{3\times 8.1}{\pi}\]whatever that is

Answer 11

yeah looks good
