-- Draw any two random chords of the circle.
-- Construct the perpendicular bisector of each chord.
-- The perpendicular bisectors intersect at the center of the circle.
All of this can be done with a compass, an unmarked straight-edge, and a pencil.

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
How do you find the diameter of a sphere?
R (radius) X2. The radius is half the circle from the center of the circle. The diameter is just straight across.
What is a center point in a circle?
Center.
A diameter of a circle has endpoints P(-10-2) and Q(46) a.)find the center of the circle b.)find the radius. if your answer is not an integer express it in radical form c.)write an eqaution for the ci?
Endpoints of diameter: (-10, -2) and (4, 6)Midpoint which is the center of the circle: (-3, 2)Radius of the circle: square root of 65Equation of the circle: (x+3)^2 +(y-2)^2 = 65
Does a diameter pass through the center of the circle?
yes a diameter passes through the center of a circle
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 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?
Draw a pizza on it, then where ever you drew the pepperoni is the center.
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
Is the center of a great circle also the center of a small circle?
No. Every circle on the sphere whose center is also the center of the sphere is a great circle. If the circle's center is not also the center of the sphere, then the circle is a small circle.
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!
How do you find the center of gravity of a circle and a rectangle?
In both cases, because of their symmetry, the center of gravity is in the geometric center.
