How can you find the center of a circle by paper folding?
:) first measure it vertically then horizontally
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.
What is a chord of a circle that contains the center of a circle?
A chord of a circle that contains the center of the circle is called the diameter.
What is the point from which all points on a circle are the same distance?
This is the center of the circle. From the center of the circle, all the points on the circle are equally distant.
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 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 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.
Find the center of a circle with the equation x2 plus y2-18x-14y plus 124?
The center of the circle is at (9, 7) on the Cartesian plane
