Question

If radius of circle is 5.2cm then find length of longest chord

Answer 1

Answer:

10.4cm

Explanation:

The longest chord of the circle is diameter.

So, diameter=2r

=>d=2×5.2cm

=10.4cm

Answer 2

Given:

If the radius of a circle is 5.2cm

To Find:

find the length of the longest chord

Solution:

A chord is a line segment joining one point of the circle with another point. The longest chord of a circle is known as the diameter of the circle through the centre of the circle.

The value of the diameter is twice the value of the radius.

For the question the length of the radius is given as 5.2cm, so the length of the diameter will be,

Diameter=2*5.2

               =10.4cm

So as the length of the diameter is 10.4cm then the length of the longest chord will also be 10.4cm.

Hence, the length of the longest chord is 10.4cm.
