Please find attached a diagram of a circle and its radius

A circle is a two dimensional figure bounded by one curved line. All the straight lines that are drawn from a certain point within it to the bounding line, are equal.

The radius of a circle is the distance from the center of a circle to its circumference.

The radius of a circle is represented by r

The circumference of a circle is the perimeter of a circle. It is the distance round a circle.

The formula for the circumference of a circle is 2πr

π = pi = 22/7

r = radius

A ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

The ratio of a circle's circumference to its radius is

2πr : r

Divide both sides of the equation by r

= 2π : 1

=
