Circle-related formulas: Circle: is the set of all points that are the same distance from a centre point. Circumference (C): the perimeter or distance around the outside of a circle (the length of the circle). C= (3.14) x d OR C=2 (3.14) r

Practice:

Diameter (d): a line segment from one side of the circle through its centre to the other side. Radius (r): a line segment from the centre of a circle to the outside of a circle. AREA OF A CIRCLE: A = r2

Practice:
