Question

find the circumference of a circle whose radius is 5 cm​

Answer 1

Answer:

31.4 cm.

Step-by-step explanation:

Circumference of circle = 2πr

Radius = 5 cm.

solution :

2 * 3.14 * 5

= 15.7 * 5

= 31.4 cm.

Answer 2

Given:

Radius is 5 cm​

To Find:

Find the circumference the circle.

Solution:

We know that,

Circumference of a circle = 2πr

Here, we have

r = 5

Substituting value of r = 5 in the above expression, we get

Circumference of a circle = 2πr

                                           = 2 x 3.14 x 5

                                           = 10 x 3.14

                                           = 31.4 cm

Hence, the circumference of a circle of radius 5 cm​ is 31.4 cm.
