Question

How to find the circumference of a circle if the diameter is 14cm?

Answer 1

Answer:

The circumference of a circle if the diameter is 14cm is 44 cm.

Step-by-step explanation:

Given : Diameter = 14 cm

Find: The circumference of a circle.

Formula:

The circumference of a circle =  π × diameter

= 22/7 × 14

= 22 × 2

= 44 cm

So, The circumference of a circle is 44 cm.

Answer 2

The give data in the question is as below

The diameter of circle=$14cm$

We have to find the circumference of a circle

As we know that ,

Circumference of a circle=$2\pi r$

Where, r= radius of circle

            Value of $\pi$ is $\frac{22}{7}$

But radius of circle is a half of diameter

Radius (r)=$\frac{Diameter}{2}$=$\frac{14}{2}$=$7cm$

So, circumference of a circle=$2 \pi r$

     Circumference of a circle=$2 \times \frac{22}{7} \times 7$

$7$ of numerator and denominator get cancelled we get,

     Circumference of a circle=$2 \times 22$

 By multiplying $2$ by $22$ we get,

      Circumference of a circle=$44$ cm

Therefore , circumference of a circle is equal to $44cm$
