Question

Two circies or radil 5cm and 3 cm intersect at two point and the distance between
their centres is 4 cm. Find the length of the common chord.​

Answer 1

Answer:

here the diameter fo two circles will be the

common chord

r1(radius of 1st circle)=5cm

r2(______of 2nd circle)=3cm

but r1+r2=8

but distance betn their centre is 4

:. circle intersect internally

distance=4

means 4is radius & diameter =2(4)=8

:. common chord is 8cm
