The circumference of a circle can be calculated using the formula C = πd, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is given as 14mm. Plugging this value into the formula, we get C = π(14) = 43.982mm. Therefore, the circumference of a circle with a diameter of 14mm is approximately 43.982mm.

The formula for circumference is pi*diameter. Thus, 3.14(pi)*14(diameter)=43.96. Therefore the circumference is 43.96.
Diameter = Circumference/pi
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
Since the circumference is Pi times the diameter then divide the circumference by Pi (3.14159) to get the diameter
Circumference = diameter(pi) so divide the circumference by pi to get the diameter.
circumference = pi*diameter or pi = circumference/diameter
