# Math Help - Find the arc length problem inquiry

1. ## Find the arc length problem inquiry

Hello,

I'm studying for my pre-cal exam tomorrow and I'm not sure about a question...

Find the length of an arc of a circle radius 8m if the arc subtends a central angle of 1 rad.

I multiplied 1 rad by pi, and reasoned that Pi= 180 degrees

Then I followed the formula, S= R*theta
S= 8*180 degrees

Usually, when an answer is this simple, I'm doing something completely wrong. How can I solve this problem?

Wait... is the answer 8... ?>.<?

Oh man I'm so confused.
