Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
-- Find the circumference of a full circle with a diameter of 12 mm.-- The perimeter of the semi-circle is(1/2 the circumference of the full circle) + (the diameter).
The perimeter or circumference of a circle = 2*pi*radius or pi*diameter
(pi) times the diameter of the circle=pi*d
24*pi or 2*pi*12 The perimeter of a circle is its circumference.
