Circle
A circle is a closed curve in which all points are equally distant from the center point. The distance from the center to any point on the circle is called the radius.
O
In the circle above, the letter "O" represents the center of the circle, and the distance from the center to the edge is the radius.
The formula to find the circumference of a circle is:
Circumference = 2 * π * radius
The formula to find the area of a circle is:
Area = π * radius2

Classify objects and count the number of objects in each category.
Classify objects into given categories; count the number of objects in each category, and sort the categories by count. (Limit category counts to be less than or equal to 10.) [K-MD3]
