Question

find the circumference of a circle whose radius is 14 cm​

Answer 1

AnSwEr :

☯ FORMULA TO BE USED : 2πr

• Here , Radius of circle is 14 cm .

➡ Therefore , $\sf 2πr\:=\:2\: \times \dfrac{22}{7} \times 14$

➡ $\sf 4 \times 22$

➡ $\sf 88\:cm$

✤ Circumference = 88 cm

Answer 2

Answer:

The circumference of the circle is $88$ cm.  

Step-by-step explanation:  

In context to the question asked,    

We have to find the circumference of a circle,  

As per data given in the question,    

We have,  

Radius ( r ) = $14$ cm  

For calculating the circumference of the circle,  

The formula to be used,  

Circumference of circle = $2\pi r$  

By substituting the values in the above formula,  

$=> 2\times \frac{22}{7}\times 14$

Now, expressing $(2\times \frac{22}{7})$ as a single fraction

$=> \frac{2\times 22}{7}\times 14$

Multiply $2$ and $22$ to get $44$,

$=> \frac{44}{7}\times 14$

Expressing $(\frac{44}{7}\times 14)$ as a single fraction

$=> \frac{44\times 14}{7}$

Multiply $44$ and $14$ to get $616$,

$=> \frac{616}{7}$

Divide $616$ by $7$ to get $88$,

$=>88cm$  

Hence circumference of the circle is $88$ cm.
