Q1. Two circles of Radii 5cm and 3cm intersect at two points and the distance between their centres is 4cm. Find the length of the common chord.Q2. three persons A, B and C are standing on a circle of radius 5m drawn in a park. A passes ball to B, B passes it to C and C passes the ball to C. AB = 6cm. BC = 6cm. Find CA.
is the ans for the first question 3 cm ?

arey question wala post dobara se padho..I have edited that. Answers nahi pata. :(
anyway......
the two radii 5 cm and 3 cm along with the dist bet the centres 4cm make a triangle with half of the chord as triangle's altitude
use heron's formulae sqrts(s-a)(s-b)(s-c)=6cm=1/2base(4cm)*alt(to be calculated)

@brixcel aur 2sra question to samajh hi ni ara likha kya hai
i think u mixed up units(cm and mtr)
read it again

2nd ka ans 6cm
2 sides of triangle 6cm each
(draw a circumcircle to the triangle abc a b c are respectively where abc are standing centre is at o
oa ob oc angle bisectors of a b c vertices 3 similar triangle ho gae
triangle aoc me base ac ki value = triangle aob ke base ab = triangle cob ka base cb = 6cm

paga ho gai hai 6 days kahan se parson paper hai
