I did this question wrong so I had to edit it.... sorry :s.
that simply means, is a vertical line, check the picture below.
Answer:
1,124.12 mm
Step-by-step explanation:
<u><em>Steps to answering this question : </em></u>
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 = nr²
where r = radius
n = pi = 3.14
100,608.7mm = nr²
to determine the radius, divide both sides of the equation by 3.14
32,040.98726mm = r²
Find the square root of 32,040.98726mm
√32,040.98726mm
r = 179mm
Circumference of a circle = 2nr
2 x 179 x 3.14 = 1,124.12 mm
