radius of a circle is 5 cm, then find the length of longest chord of a circle.
radius of a circle is 5 cm, then find the length of longest chord of a circle.
Answer: The length of the longest chord of a circle is equal to the diameter of the circle. The diameter is twice the radius of the circle.
So, in this case, the radius of the circle is 5 cm. Therefore, the diameter is:
Diameter = 2 x radius = 2 x 5 cm = 10 cm
Hence, the length of the longest chord of the circle is 10 cm.
