hello, any help would be appreciated (:

'A sheep is tethered to a post which is 6 m from a long fence.

The length of the rope is 9 m.

Find the area which is available for the sheep to feed on'

I know the formula to find a segment, but that'd require that I had the angle, and I dont, so I'm sorta at a loss...

Thanks again for any help
