The diameter of circle is 1.018 mm.
Step-by-step explanation:
Given,
Circumference of circle = 3.2 mm
We know that;
Circumference = 2πr
[tex]3.2=2\pi r\\[/tex]
Putting π=22/7
[tex]3.2=2*\frac{22}{7}*r\\3.2=\frac{44}{7}r[/tex]
Multiplying both sides by 7/44
[tex]\frac{7}{44}*3.2=\frac{7}{44}*\frac{44}{7}r\\\\\frac{22.4}{44}=r\\\\r=0.509[/tex]
Diameter = 2r
Diameter = 2*0.509
Diameter = 1.018 mm
The diameter of circle is 1.018 mm.
