Two circles of radii 5 cm and 3 cm intersect at two points and the distance between their centres is 4 cm. Find the length of the common chord.I want the accurate ans with step by step solution.plsss.....
dewanaaryan1:
i think the distance bw their centres must be greater tun 5 cm ! otherwise the question is wrong!!
never the question is wrong,the center of the smaller circle may be inside the larger circle
Hey then those are concentric circles... you must mention that thing!
it is not concentric,it meets at 2 points
i a m sorry let me give u the ans

i am sorry for the wrong and i gave.... this is a simple question with a trick!
we can find the area of triangle abe by herons formula. We know that
= 90 degree. so in triangle abc area can be found by 1/2 bh. we know the base and the area so we can get the height! so we will obtain AC similarly we will get CD and then add them!

what is the base?
ok,leave it..let me do.
u said the distance between their centres is 4 cm ..that is the base yr... se the figure properly!
4,3 and 5 are the sides,so we can do it by heron'sformula;right?
w i got it.i suddenly mistook the formula to another
thanks again
no problem!
:)
This is called a genius answer!!!
