Question

The radius of a circle is 6.1 cm. Find the length of the longest chord of the
circle.

Answer 1

Answer:

the longest chord will be diameter of circle

so 2radius = diameter

2×6.1 cm = diameter

diameter = 12.2cm

therfore longest chord is 12.2cm.

Answer 2

Answer :-

• The longest chord of the circle = 12.2 cm.

Given :-

• The radius of a circle is 6.1 cm.

To find :-

• The length of the longest chord of the circle.

Step-by-step explanation :-

• It has been given that the radius of a circle is 6.1 cm.
• We have to find the length of the longest chord of the circle.

⇒ We have already learnt that the longest chord of a circle is it's diameter.

• So, we have to find the diamter of the circle.

-------------------

We know that :-

$\overline{\underline{\boxed{\sf Diameter = 2 \times Radius.}}}$

Here,

• Radius = 6.1 cm.

Hence,

$\boxed{\rm Diameter = 2 \times 6.1}$

Multiplying 2 by 6.1,

$\overline{\boxed{\rm Diameter = 12.2 \:cm.}}$

-------------------

• So, the diameter of the circle = 12.2 cm.

• Hence, the longest chord = 12.2 cm.
