Answer 2

To find : diameter of circle .

Given : radius of circle is $4.3\ cm$

Solution :

• As per the given data we know that  radius of circle is $4.3\ cm$ .We have to find diameter of circle .
• We know that diameter of circle is twice of radius .

       i.e. Diameter  $= 2$ radius  

• Hence , multiplying radius by $2$ to find diameter of circle .

• Diameter = $2 \times 4.3\ cm$

                        $= 8.6 \ cm$

Hence , diameter of circle is $8.6\ cm$ .
