The circles having radii r1 and r2 intersect orthogonally Length of their common chord is

Let two circles having radii r_(1) and r_(2) are orthogonal to each other. If the length of their common chord is k times the square root of harmonic mean between the squares of their radii, then k^(4) is equal to

Two circles whose radii are equal to 4 and 8 intersect at right angles.The length of their common chord is-

There are two orthogonal circles with radii 5 and 12 units,t hen the length of their common chord is

Two circles of radii 15 cm and 10 cm intersecr each and the length of their common chord is 16 cm. What is the distance (in cm) between their centres ?

Circles of radii 3 and 4 intersect orthogonally The area common to the two circles is

If the angle of intersection at a point where the two circles with radii 5 cm and 12 cm intersect is 90^(@) , then the length (in cm) of their common chord is

Two circles of radii 10cm and 8cm intersect and the length of the common chord is 12cm. Find the distance between their centres.
