First determine the radius of the circle from the area of the circle
Use the radius determined above to calculate the circumference
Area of a circle = np2
where r= radius
n= pi = 3.14
100.608.7mm=mp2
to determine the radius, divide both sides of the equation by 3.14
32,040.98726mm = p2
Find the square root of 32,040.98726mm
V32,040.98726mm
r= 179mm
Circumference of a circle = 2nr
2 × 179 × 3.14 = 1.124.12 mm
Hope this helps
