Question

the length of a chord passing through the Centre of the circle is 10 cm. What is the radius of the circle?​

Answer 1

_______________________________________

Answer:

• Radius of the circle = 5cm.

Given:

• The length of a chord passing through the Centre of the circle is 10 cm.

To find:

• The radius of the circle?

Let's understand:

If the length of the chord is passing through the centre of the circle it is diameter.

• The length of the centre of the circle is called the diameter.

Solution:

As the diameter is 10cm.

As we know:

$\boxed{ \sf Radius = \frac{1}{2} \times 10cm.}$

Let's do:

Radius = 0.5 × 10cm.

Radius = 5cm.

Hence , Radius if the circle = 5cm.

Answer 2

Given:-

• The length of a chord passing through the centre of the circle is 10cm

To Find:-

• Radius of the circle = ?

Solution:-

As the diameter is 10 cm.

We know that,

$\sf\pink{Radius={\frac{1}{2}×10cm}}$

Radius = 0.5 × 10 cm

Radius = 5cm

Hence,Radius if the circle = 5cm.
