Two each circles of radius 13 cm intersect each other and the length of their common chord is 10 cm. find the distance between the centre of the circle.

Two equal circles with radius 10cm. Intersect each other and the length of their common chord is 12cm. Find the distance between two centres of two cricles.

The co-ordinates of two points P and Q are (x_1,y_1) and (x_2,y_2) and O is the origin. If circles be described on OP and OQ as diameters then length of their common chord is

Two circles C_1 and C_2 intersect in such a way that their common chord is of maximum length. The center of C_1 is (1, 2) and its radius is 3 units. The radius of C_2 is 5 units. If the slope of the common chord is 3/4, then find the center of C_2dot

Two circles having radii r units interest each other in such a way that each of them passes through the centre of the other. Then the length of their common chord is ____

If theta is the angle between the two radii (one to each circle) drawn from one of the point of intersection of two circles x^2+y^2=a^2 and (x-c)^2+y^2=b^2, then prove that the length of the common chord of the two circles is (2a bsintheta)/(sqrt(a^2+b^2-2a bcostheta))

If two concentric circles are of radii 5 cm and 3 cm, then the length of the chord of the larger circle which touches the smaller circle is___
