Get area of circle on positive side of a cartesian axis system

Description

Calculate the area of a circle that lies on the positive side of a two-dimensional cartesian coordinate system

Usage

circle_area_positive(x, y, d)

Arguments

x, y	x, y position of the circle midpoint (scalar)
d	diameter of the circle

Value

area (scalar)

Examples

#complete on positive sides
circle_area_positive(1, 1, 2)

#crossing x-axis only
circle_area_positive(0, 1, 2)
circle_area_positive(-0.5, 1, 2)

#crossing y-axis only
circle_area_positive(1, 0, 2)

#crossing both axes
circle_area_positive(0.5, 0.5, 2)
circle_area_positive(-0.5, -0.5, 2)

#fully on negative side
circle_area_positive(-1, -1, 2)
