Question

· Distance of chord AB from the
centre of a circle is 8 cm.
Length of the chord AB is
12 cm. Find the radius of
the circle.​

Answer 1

Step-by-step explanation:

perpendicular drawn from center of a circle to chord divides the chord into equal parts

AD=BD

using pythgoreas theorem

r²=OD²++AD²

r²=8²+6²

r=10 cm
