## What is Area of a Circle when diameter is given?

Area of a circle when radius is given is the region occupied by the circle in a two-dimensional plane of diameter "d". Although often referred to as the area of a circle in informal contexts, strictly speaking the term disk refers to the interior of the circle, while circle is reserved for the boundary only, which is a curve and covers no area itself. Therefore, the area of a disk is the more precise phrase for the area enclosed by a circle.
