Question

What is the circumference of a circle of diameter 5 cm (Take π = 3.14)?​

Answer 1

Answer:

the circumference of a circle= 2πr = π d

here, d = 5 cm

therefore, the circumference of a circle= π × 5 cm

= 3.14 × 5 cm

= 15.7cm.

Answer 2

Answer:

Circumference  of circle is $15.7$ cm .

Step-by-step explanation:

To find : circumference  of circle taking (π = 3.14) .

Given :  diameter of circle is $5$ cm .  

Solution :

• As per given that we know that  diameter of circle is $5$ cm . We are asked to find circumference of circle,  
• As we know that diameter is twice of radius ,

• i.e. $diameter } =2 r$  

                           $5 = 2r \\\\r =\frac{5}{2} \\\\ r = 2.5 \ cm$

• Using following formula we find  circumference  of circle .

        Circumference of circle $= 2\pi r$  

                                                $= 2\times 3.14 \times 2.5\\\\ = 15.7 \ cm$
