Question

does anyone know how to do this? picture coming

Answer 1

isn't the formula s = angle r used?

the angle is 5pi/3 and the radius is 9
so

s = (9)(5pi/3) = ?

Answer 2

oh yeah it does use it

\[s = \theta r\]
since
\[\theta = \frac{5 \pi}{3}, r = 9\]

Answer 3

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

Answer 4

47.1!

Answer 5

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