Q6 of 9 Page 32

A chord of a circle is 30 cm long. Its distance from the centre is 8 cm. Find the radius of the circle.

Given: distance of the chord from the centre =

Length of chord


By, Given information we will draw a circle.



Here, distance of the chord from the centre


Length of chord


Where, AD is perpendicular bisector of chord BC


Thus,


Join, AB, we get



Since,


Therefore, we will use By Pythagoras formula







Thus, radius of a circle
