I need some help with some of my homework, I can't figure it out.
I have a radius on a circle and a height from the circle to the chord.
I found this formula $ h=r \left(1-\cos \frac{v}{2} \right) $ And isolated it to $ v = \arccos \left( \frac{h/r -1}{2}\right) $ Not sure if that's correct. Then I input it in this formula $ A=r^2((\pi v)/360-(\sin v)/2) $ I have tried with a radius of 1000 and a height from the circle to the chord of 1000.
But it gives a wrong result.
