Draw a chord, then construct a line perpendicular to the center of the chord; it passes through the center of the circle. Do this again with a different chord and the intersection of the two perpendicular lines is the center of the circle.
To find the center of a circle in woodworking, draw two diagonal lines from opposite corners of the circle. Where the lines intersect is the center of the circle.
To find the center of a circle for drilling, you can use a compass to draw two intersecting lines across the circle. The point where the lines meet is the center of the circle. You can then mark this point for drilling.
measure it
Draw a cord through the circle (a line through the circle, but not too close to where you imagine the center to be). With construction techniques, find the perpendicular at the center point of the cord, and draw the perpendicular. Do the same thing again starting with a different cord, and the two perpendiculars will intersect at the center of the circle.
Draw a pizza on it, then where ever you drew the pepperoni is the center.
It'll be the largest chord of the circle.
The easiest way to find the radius (measurement from the outside to the center of a circle) is to measure the diameter and divide by 2.
# Find the center of the circle # Draw the line of the radius from the center to the circumference # Finish
You would have to know the length of the radius. The center of the circle is at one end of the radius. If you just know where some part of the radius is, and not that the part touches the circle then you cannot know where the center is without at lest a point on the circumference.
a diameter
You cannot. The circle could be located anywhere on a plane.
it is the intersection of the medians of two cords!
