Question

How long is the longest chord in a circle of radius 2006 mm?

• A. 4012 mm
• B. 2014 mm
• C. 2048 mm
• D. 6002 mm

Answer 1

The correct option is A 4012 mm

The longest chord of a circle is its diameter, which is twice the radius of the circle.
i.e., Diameter = 2$\times$ Radius
= 2$\times$ 2006 mm
= 4012 mm
Thus, the longest chord of the circle is 4012 mm long.
