In a circle of diameter 40 cm. The length of a chord is 20 cm. Find the length of minor arc of the chord.

Text Solution

Verified by Experts

Diameter of the circle =40 cm ∴ Radius (r) of the circle = `40/2 cm` ​
`=20 cm`
Let AB be a chord (length = `20 cm`) of the circle. In `△OAB, OA = OB` = Radius of circle = `20 cm`
