Step-by-step explanation:
A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant. The distance between any point of the circle and the centre is called the radius.
Let B be the centre of the circle
Let AB =r units be the radius ie., distance between A and B
where AC is the diameter of the circle

Step-by-step explanation:
when you multiply by a ten (10, 100, 1000, etc.), just add a zero for each zero. it's the same when you divide: for every zero in the ten, you remove a zero.
