May 23, 2021 · The distance around a circle is its circumference. The distance from the center to the circle is its radius. The longest distance between two points on a circle is the diameter, which is a line segment running through the center. A circle is the shape with the shortest perimeter enclosing an area.
Center (or origin): the point within a circle that is equidistant from all other points on the circle. Radius: the distance between any point on the circle and the center of the circle. It is equal to half the length of the diameter.

The area of a circle is the amount of space enclosed within the boundary of a circle. The region within the boundary of the circle is the area occupied by the circle. It may also be referred to as the total number of square units inside that circle. Area of Circle = πr2 or πd2/4 in square units, where. (Pi) π = 22/7 or 3.14.
Circle: the set of all points on a plane that are a fixed distance from a center. Area. The area of a circle is π times the radius squared, which is written: A = π r 2. Where. A is the Area. r is the radius. To help you remember think "Pie Are Squared" (even though pies are usually round):
Jan 16, 2023 · Area of a circle formula. If you know the radius, r, in whatever measurement units (mm, cm, m, inches, feet, and so on), use the formula \pi {r}^ {2} πr2 to find area, A: A=\pi {r}^ {2} A = πr2. The answer will be square units of the linear units, such as m {m}^ {2} mm2, c {m}^ {2} cm2, {m}^ {2} m2, square inches, square feet, and so on.
5 days ago · A circle is the set of points in a plane that are equidistant from a given point . The distance from the center is called the radius, and the point is called the center. Twice the radius is known as the diameter . The angle a circle subtends from its center is a full angle, equal to or radians.
