solution :Chord is a line segment which connects the two points lie on the circle. In a circle the largest chord is known as diameter.
Diameter is twice of its radius. If the radius of the circle is r, the diameter is 2r.
The radius of the given circle is 3 cm.
r=3r=3
d=2rd=2r
d=2\times 3=6d=2×3=6
Therefore the length of the largest chord of the circle with radius 3 cm is 6 cm.
Answer : 6 cm
