Radius; Perimeter and Area

Explanation

What is a Circle?

A circle closed plane geometric shape. In specialized terms, a circle is a location of a point surrounding and moving at a fixed distance away from the stationary point. It may be considered as anything which is round. The distance of a peripheral point from the centre point is the radius of the circle. Let us look at some properties and terms associated with the circle.

Radius of Circle

It is the line which connects the centre point of the circle and the circumference of the circle. It is typically represented by 'r' or 'R'. The radius value is used in determining the area and perimeter of the circle. We will look at some solved examples in the end.
