Radius of a circle is any line from the center of the circle to the circumference of the circle. A diameter is the sum of two radius within the circle. Any line apart from the diameter inside the circle is refe
Learn to define the radius of a circle. Learn what the radius formula is and how to find the radius of a circle given area, diameter, or...
C =πd … circumference of a circle using diameterThis gives us the formula for the circumference of a circle when the diameter is given.Also, we know that the diameter of the circle is twice the radiusor, d =2rSo, replacing the value of d in the above formula, we get:C =π(2r...
Area of a Circle = πr2 square units A = πr2 square unitsWhere A = the area of a circle. pi (π) = 22/7 or 3.14 and r = the radius of a circle. Let’s get a better understanding of this formula by working out a few example problems. ...
Radius: The radius of the circle is a line segment that joins the centre and any point on the Circumference.Diameter: The diameter of the circle is the line segment starting from any point on the circumference of the circle, passing through the centre and ending at the point on the ...
All those points for which the distance is equal to that of the radius of a circle lie on the circle. For example points U and V lie on the circle. Semicircle: Semi means half, so semicircle ishalf a circle. It is formed by cutting a whole circle along a line segment passing through...
There are many parts of a circle that define a circle such as a radius, a diameter, a chord, and so on. Learn more about the parts of a circle, its formulas, and solve a few examples.

The area of a circle is calculated with the help of the formula: Area of circle = πr2. If the diameter is given we can find the radius by dividing the value of diameter by 2. After getting the radius, we can substitute its value in the formula: Area of circle = πr2to get the...
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 ...
