The following are the general steps to draw a hexagon inscribed in a circle:
First draw a circle with center A through B:
Then the intersection points will be vertex C and vertex D of the hexagon. Doing this for each vertex (from left to right) we will get the following:
We are given an equation:
This is an equation of a circle. General form of a circle equation is:
Where:
a = x coordinate of a center
b = y coordinate of a center
r = radius of a circle
Motion detector can detect person anywhere within a boundary. The greatest distance at which detector can detect is at the edge of a circle. That distance, between detector and edge of circle, is equal to radius.
From the equation we have:
The greatest distance at which person can be detected is 4ft.
