Question

what is circle and formula​

Answer 1

Answer:

A circle is a shape consisting of all points in a plane that are a given distance from a given point, the centre; equivalently it is the curve traced out by a point that moves in a plane so that its distance from a given point is constant.

Here Origin of the circle = O , Diameter = D and Radius = r. Area of a circle (A ) = π r 2 =( π/4 ) D2 = 0.7854 D2. Circumference of a circle ( C ) = 2 π r = π D. Area of circle =( 1/2) x Circumference x radius.

Answer 2

Step-by-step explanation:

The formula to find area of a circle is 3.14 or 22/7×radius×radius

The formula to find circumference of a circle is 2×3.14 or 22/7 ×r
