What is a circle?

A circle is a curve sketched out by a point moving in a plane so that its distance from a given point is constant; alternatively, it is the shape formed by all points in a plane that are at a set distance from a given point, the centre.

The area of the circle with a diameter of 240 mm is,

Area of circle = (π/4) × D²

                       = (π/4) × (240)²

                       = 45238.934 mm²

Hence, the area of the circle with a diameter of 240 mm is 45238.934 mm².
