Question

If the length of the chord is 16 cm and is at the distance of 15cm from the center of the circle , then the radius of the circle is = ?​

Answer 1

Answer:

Here by using Pythagoras theorem

(radius)^2 = (15)^2 + (8)^2

= 225 + 64

= 289

radius. = 17

Hence your answer is 17

and the 8 is there because the line joining the center to the chord bisect the chord.
