of a circle is a straight line segment whose endpoints both lie on the circle.

# data[].attributes.body
A line which touches a circle or ellipse at just one point.

# data[].attributes.body
of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also the length of any of them.

Circumference of a circle-
C=2πr

Aera of a circle-
A=πr2

Standard form of the equation of a circle-
(x – h)² + (y – k)² = r²

Arc length-
r=2π10

Aera of a sector-
aera = (Angle/360)*Pi*r^2.
