And if the area of a circle is known then the formula for radius is the square root of the area divided by pi. How do you find the radius and diameter of a circle? Measure the length from the center of a circle to a point on the boundary of a circle. That measure will give the...
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 point. Knowing how to calculate a circle's circumference can be useful in math ...
How to Find the Central Angles and Inscribed Angles of a Circle Step 1: Determine if the vertex of the angle in question lies at the center of the circle or on the circle. This will determine if the angle is central or inscribed. Step 2: Identify the measurement of the arc ...
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...
