isn't the formula s = angle r used? the angle is 5pi/3 and the radius is 9 so s = (9)(5pi/3) = ?

3. UsukiDoll

oh yeah it does use it $s = \theta r$ since $\theta = \frac{5 \pi}{3}, r = 9$

4. UsukiDoll

$s= \frac{5 \pi}{3}(9) \rightarrow \frac{45 \pi}{3}$

47.1!

$45 \times \pi = 141.37$ $\frac{141.37}{3} = 47.12$ yes it is ^^... I got an extra number but it is 47.1
