# Height of the arc - formula

Calculate the height of the arc if the length of the arc is 77 and chord length 40.
Does exist a formula to solve this?

h =  26.55

### Step-by-step explanation:

α0= 1.5707963267949 = 90°; r = 49.019722472304; h = 14.358
α1= 2.7223611075682 = 155°58'47″; r = 28.284271247462; h = 22.399
α498= 3.7005941597357 = 212°1'42″; r = 20.807469470119; h = 26.548
α499= 3.7005941597357 = 212°1'42″; r = 20.807469470119; h = 26.548 Did you find an error or inaccuracy? Feel free to write us. Thank you! Tips to related online calculators
