wardahd1234: give me the solution please

chetanabhojwani: Find the area of the triangle with the centre and the end points of the chord by area of equilateral triangle formula(root3 by 4× side^2) and then equate it to the area of the same triangle with formula being half×base×perpendicular height(construction) of the triangle. The you will find the perpendicular height in terms of r
