Oh, dude, you're hitting me with some math here. So, the circumference of a circle is calculated by multiplying the diameter by pi (π). Since the diameter of a circle is twice the radius, and you've given me the radius (40 mm), I can tell you that the circumference of a 40 mm circle would be approximately 251.2 mm. It's like math, but with a side of sarcasm.

If the diameter of a circle is 3mm the circumference is: 9.424 mm
What is the radius of a circle with a circumference of 6.28 mm?
Radius of the circle: 6.28/2*pi = 0.999 mm or about 1 mm
The circumference of a circle is 40 pi cm what is the radius of the circle in 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)
What is the radius of a circle whose circumference is 40 pi?
The radius of a circle whose circumference is 40pi is 20 units.
