Question

If the Diameter of Circle is 28 cm.
then Find its cirmuference​

Answer 1

Given:

Diameter of the circle = 28 cm

To Find:

Circumference of a circle = 2πr

where, r is radius and π is pi = 22/7

Explanation:

Circumference = 2 × 22/7 × 28/2

Circumference = 22/1 × 4

Circumference = 88 cm

Answer:

The circumference of the circle is 88 cm .

Answer 2

Given :-

• Diameter of circle = 28 cm

To Find :-

• What is the circumference of circle ?

SoLuTioN :-

Let's find out radius ,

as you know

• r = d/2

Now,

putting the values in the above formula we get,

↠ r = 28/2

↠r= 14 cm

As we know that :-

• Circumference of a circle = 2πr

where,

r = radius

π = pi

Now,

putting the values in the above formula

↠ Circumference = 2 × 22/7 × 14

↠ Circumference = 2 × 22 × 2

↠ Circumference = 88 cm

Hence, the circumference of the circle is 88 cm .
