Question

please answer by solving​

Answer 1

Given :-

Circumference = 22/7 cm

To Find :-

Radius

Solution :-

We know that

Circumference = 2πr

22/7 = 2 × 22/7 × r

22/7 = 44/7 × r

22/7 ÷ 44/7 = r

22/7 × 7/44 = r

22/44 = r

1/2 = r

Option B is correct!

Answer 2

Answer:

• 1/2 cm is the radius of circle.

Step-by-step explanation:

Given :

Circumference of circle = 22/7 cm.

To find :

Radius of circle.

Solution :

• Circumference = 22/7 cm

⇒ 2πr = 22/7

⇒ 2 × 22/7 × r = 22/7

⇒ 44/7 × r = 22/7

⇒ r = 22/7 × 7/44

⇒ r = 22/44

⇒ r = 11/22

⇒ r = 1/2

∴ Radius of circle is 1/2 cm.
