Wait... is the answer 8... ?>.<?
Oh man I'm so confused.
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
My answer was 1440.
Usually, when an answer is this simple, I'm doing something completely wrong. How can I solve this problem?
Thanks in advance.
