You do not know how to find the centre of a circle. But can you find the centre of a equilateral triangle. If your answer is yes, then you make a concentric circle and a triangle. Let me explain.
First take a random point on the circle.
Now from that point draw two 60 degree angles. Then take the two points where those 60 degree angles meet the circumference. Now you have three points. Now join them. You get an equilateral triangle.Now take an angle and bisect it. Do the same with the other two angles. Are they not concurrent (meet at a same point?) Well now the place they meet is the centre of the triangle. And since the centre of the triangle and the circle is same, that is the centre.
:) first measure it vertically then horizontally
Draw a pizza on it, then where ever you drew the pepperoni is the center.
the radius is from the center of the circle to the edge so that's how you find the radius.
Equation of the circle: (x-3)^2 +( y+13)^2 = 169
to be honest I dont know
:) first measure it vertically then horizontally
measure it
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.
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.
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.
# Find the center of the circle # Draw the line of the radius from the center to the circumference # Finish
a diameter
You cannot. The circle could be located anywhere on a plane.
it is the intersection of the medians of two cords!
