Two equal circles pass through each other’s centre. If the radius of each of the circles is 13 cm, then what is the length of the common chord?
13√3 cm
The length of the common chord of two equal circles passing through each other's centre can be calculated using the formula derived from geometry, which gives the result 13√3 cm.
