Question

The radious of acircleis 8 cm and the lenth of a circle onr of its cords is 12 cm find the

Answer 1

dear mate, the question is incomplete , but i assume that we have to find the distance of the chord from centre , therefore i have given an answer that :))

Draw a perpendicular on the given chord from the center of the circle

we know it divides the chord in to equal parts

Join the centre of circle and end point of the chord

you will get right angled triangle

let the distance be x

using Pythagorean theorem

8²=6²+x²

64=36+x²

x²=28

x=√28

x=2√7
