Question

videos of the circle with centre 0 is 25 CM find the distance of a chord from the centre if length of the chord is 48 CM

Answer 1

Answer:

Let the chord be AB=48

Let the middle point of AB be C and the centre of the circle be O

Then the distance =√OA^2 - (AB/2)^2

=√25^2 - 24^2

=√625-577

=√49
