					 Chords AB and CD of a circle intersect at E and are perpendicular to each other. Segments AE, EB and ED are of lengths 2 cm, 6 cm and 3 cm respectively. Then the length of the diameter of the circle (in cm) is
- 
                        - √65
-  1 √65 2 
- 65
-  65 2 
 
Correct Option: A
As per the given in question , we draw a figure circle 
Given , AE = 2 cm 
EB = 6 cm 
ED = 3 cm 
∴ AE × EB = DE × EC
| ⇒ EC = | = 4 cm. | |
| 3 | 
∴ Diameter = √7² + 4² = √49 + 16 = √65 cm
