The diameter of a circle is 2 times its radius:
D = 2R;
D = 2 * 2.5 = 5 (cm).
The diameter of a circle is essentially its largest chord, which connects two points on the circle and passes through its center. Thus, the chord of a circle given by the condition cannot be more than 5 cm. Since 6 cm> 5 cm, the chord of a circle cannot have a length of 6 cm.
Answer: D = 5 cm, no, the chord of a circle cannot have a length of 6 cm.
