Question: How to Find the Circumference of a Circle with Radius r = 8 cm ?

The circumference of a circle is the perimeter of the circle. It is the total length of the boundary of the circle

Answer: The Circumference of a Circle with Radius r = 8 cm is approximately equal to 50.29 cm

Circumference of a circle can be found using the formula, C = 2πr

Explanation:

Given, Radius of the circle r = 8 cm

We know that,

Circumference C=2πr

= 2×(22/7)×8 {Using π = 22/7}

= 352/7

≈ 50.29 cm

Thus, circumference Formula: C = 2πr and here the circumference is ≈ 50.29 cm

Answer 2

Answer:

The circumference of the circle is $50.2$ 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 ) = $8$ cm  

For calculating circumference,  

The formula to be used for,  

Circumference = $2\pi r$  

By substituting the values,  

$=> 2\times \frac{22}{7}\times 8$

$=> 50.2cm$  

Hence circumference of the circle is $50.2$ cm.
