Radius of the circle: 6.28/2*pi = 0.999 mm or about 1 mm
It is approx 1 mm.
A circle with a radius of 6 mm has a circumference of 37.7 mm
The circumference of a 40 mm circle is: 126 mm
If the diameter of a circle is 3mm the circumference is: 9.424 mm
The radius if the circle is half of its diameter and so 30/2 = 15 mm
C = 2pir (substitute 40pi cm for C) 40pi cm = 2pir (divide by 2pi to both sides) 20 cm = r = 200 mm (since 1 cm = 10 mm)
A circle with a radius of 6 mm has a circumference of 37.7 mm
A circle with a radius of 15.5 mm has a circumference of 97.39 mm.
The circumference of a circle, if the radius is 5mm, is about 31.42mm
The area and circumference of a circle with a radius of 9.5 mm are:A = 284mm2C = 59.7mm
28.27 mm
27.2 mm
C = ~226.195 mm
94.248 mm
Circumference = 2*pi*4 mm or 8*pi mm
188.40 mm
It is approx 302 mm.
C = 69.115 mm
