13 mm. The radius of a circle is 1/2 of the diameter.
Circumference = 2*pi*4 mm or 8*pi mm
If the diameter of a circle is 5.4mm, then the radius is 2.7 mm. The formula for the area of a circle is PIr^2. So, the area is then 22.9 mm2.
If the diameter is 25 mm then the circumference is 78.54 mm.
If the diameter of a circle is 5.4mm, then the radius is 2.7 mm. The formula for the area of a circle is PIr^2. So, the area is then 22.9 mm2.
Radius of the circle: 6.28/2*pi = 0.999 mm or about 1 mm
13 mm. The radius of a circle is 1/2 of the diameter.
The radius if the circle is half of its diameter and so 30/2 = 15 mm
It is: 1060/2 = 530 mm
~12.56
