The formula is used to find the diameter of circle is: 
The diameter of circle is 5.1 cm
<em><u>Solution:</u></em>
Given that,
Circumference (C) of a circle is 16 cm
<em><u>The formula for circumference of circle when diameter is given is:</u></em>

<em><u>Rearrange the formula to get "d"</u></em>
Divide both sides by 3.14

The above formula is used to find the diameter of circle
Given that, circumeference = C = 16 cm
Substituting we get,

Thus diameter of circle is 5.1 cm
