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.

How can you find the center of a circle by paper folding?
:) first measure it vertically then horizontally
How do you find center of a circle?
Draw a pizza on it, then where ever you drew the pepperoni is the center.
Describe the effect on the area of a circle when the radius is doubled?
the radius is from the center of the circle to the edge so that's how you find the radius.
The center of a circle is located at c(3-13). The x-axis is tangent to the circle at (30). Find the equation of the circle?
Equation of the circle: (x-3)^2 +( y+13)^2 = 169
How do you find the center or midpoint of a circle given one endpoint of the diameter?
to be honest I dont know

How do you find the radius of the circle when you know the center and a point on the circle?
measure it
How do you find the centre of a circle given part of a radius?
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.
How do you find the center point of a circle?
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.
How do you find center of a circle?

How do you find the length of diameter when the center of the circle is unknown?
It'll be the largest chord of the circle.
Measuring to the center of a 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.
What would be a quick way to find the center of the circle?
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.
How do you get a radius?
# Find the center of the circle # Draw the line of the radius from the center to the circumference # Finish
What is a chord passing through the center of a circle?
a diameter
How do you find center of the circle with radius only?
You cannot. The circle could be located anywhere on a plane.
How do you find the center of a circle?
it is the intersection of the medians of two cords!
