The endpoints of a of a circle are Q(, ) and R(,).
in order to find a , we need to find the distance between Q(, ) and R(,)

Solved by pluggable solver: Distance between two points in two dimensions

The distance (denoted by d) between two points in two dimensions is given by the following formula:

Thus in our case, the required distance is

For more on this concept, refer to Distance formula.

so, a of a circle is:
if radius is , then
so, the area will be:

..round it to whole number
