Answer 2

Answer:

The circumference of the circle is $62.8$ 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 ) = $10$ 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,  

$=> 2\times \frac{22}{7}\times 10$

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

$=> \frac{2\times 22}{7}\times 10$

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

$=> \frac{44}{7}\times 10$

Expressing $(\frac{44}{7}\times 10)$ as a single fraction

$=> \frac{44\times 10}{7}$

Multiply $44$ and $10$ to get $440$,

$=> \frac{440}{7}$

Divide $440$ by $7$ to get $62.8$,

$=>62.8cm$  

Hence circumference of the circle is $62.8$ cm.
