Answer:

C ≈ 251.33

Step-by-step explanation:

The circumference of a circle is C = 2πr

Radius = r = 40 is given in the problem

C = 2* 3.14 * 40

C ≈ 251.33

Answer:

251.2

Step-by-step explanation:

Given,

Radius ( r ) = 40

To find : Circumference of a circle = ?

Formula : -

Circumference of a circle = 2πr

Note : -

The value of π is :

  • 22 / 7 ( in fraction ).
  • 3.14 ( in decimal ).

Solution : -

Circumference of a circle = 2πr

= 2 x 3.14 x 40

Circumference of a circle = 251.2

Therefore,

Circumference of a circle is 251.2
