I swear to crappiness we've done this before ._. why do you keep on putting in repeats

snowflake0531:

anyways the arc length formula is \[2\pi r(\frac{\theta}{360})\]

kekeman:

I have not done this before this is a new question

snowflake0531:

then it was another person -.-

snowflake0531:

anyways,

kekeman:

All these circle math is similar and it's so annoying

snowflake0531:

you have diameter, so find radius, then you can use theta and the radius and use the arc length formula, as written above

snowflake0531:

\[30\pi(\frac{42}{360})\]

kekeman:

To find the circumference: C=2πr Ok so c=2pi(15)=94.24

snowflake0531:

... Just put them all together do this

kekeman:

so 42/360 x 94.24?

kekeman:

I think the answer would be "10.99 "

snowflake0531:

yes
