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

Answer:
Volume of 3% alcohol = 80 ml
Volume of 8% alcohol = 120 ml
Step-by-step explanation:
Final volume of 6% alcohol solution = 200 ml
Let the volume of 3% alcohol volume = a ml
Therefore, volume of 8% alcohol = (200 - a) ml
Equation for the given situation will be,
3a + 8(200 - a) = 6×200
3a + 1600 - 8a = 1200
1600 - 5a = 1200
5a = 400
a = 80 ml
Therefore, volume of 3% alcohol to be used = 80 ml
And volume of 8% alcohol to be used = (200 - 80) = 120 ml
