idk sorry not good at that stuff

Answer 5

its like 3.14 divide by 2 or somethiing????

Answer 6

\[L=\frac{\pi*R}{ 90 }\left[ 180-\cos^{-1} \left( \frac{ R-r }{ l } \right) \right]+\frac{ \pi*r }{ 90 }\cos^{-1} \left( \frac{ R-r }{ l } \right)+2\sqrt{l^{2}-\left( R-r \right)^{2}}\]

Answer 7

that's the answer
