Answer:
26 cm
Step-by-step explanation:
Join the center of circle with the chord at its mid point and the end points thereby forming a triangle. Hypotenuse of this triangle will be equal to 13 which will be the radius of the circle.
Diameter = radius × 2 = 13 × 2 = 26cm
use the Pythagoreans method
AB= 10 then, radius = 10/2= 5
and height is 12cm
12²+5²
144+25 = 169
square root of 169 is 13
then, radius is 13
diameter is double of radius so 13×2= 26
