You can find the circumference of a circle by using the measurement of its diameter, radius or area. The circumference of a circle is the distance around the circle's edge from one point, meeting back at that p
The center of the circle on a graph is the point that is equidistant from every point on the circle. In other words, it's the point in which the distance from the center to a point on the circle is the radius r. How do you find the center and radius of a circle? First, we ...
Find the equation for the circle using the formula (x-h)^2 + (y- k)^2 = r^2, where (h, k) is the point corresponding to the center of the circle on the (x, y) plane and r is the length of the radius. For example, the equation for a circle with its center at the point...

1. Note the Radius The radius is the fixed distance from the center of a circle to any point on its circumference. Record the radius of the circle 2. Multiply Radius by Two The radius of a circle always equals half of its diameter, so to find the diameter, multiply the radius by two...
In particular, the length of an arc of a circle of radius 'r' that subtends an angle θ at the center is calculated by the formula rθ × (π/180) if the angle is in degrees and if the angle is in radians, then the arc length is rθ. Let 's see how to derive these formul...
