Circular Area

The circle area is πr², where r is the circle's radius and π = 22/7 or 3.14 (maybe used interchangeably for problem-solving purposes). Thus, an area of the circle is nothing but is the ratio of a circle's circumference to its diameter.

A circle's circumference

A circle's perimeter is the linear distance travelled around the circle. The perimeter of a circle is known by a unique name, Circumference. The circumference multiplied by the diameter is given by the formula 2πr.

A Circle's Segment

A circular segment is a section of a circle "separated" from the portion of the circle by a secant or chord.

A circle's sector

A circle sector is the portion of a circle bounded by an arc and two radii. The smaller region is referred to as the minor sector, while the larger area is the major sector.
