#### Circle Formula:

Area of Circle = πr²
Diameter of Circle = 2r
Circumference of Circle = 2 πr = πd
Area of Sector = πr² (θ/360)
**Where, **
r = radius
This circle calculator apart from finding the diameter, area of sector, radius, circumference of the circle, also provides you the individual formulas for the calculation of the same. A circle is the set of all points in a plane at a fixed distance, called the radius, from a given point, the center. The radius is the distance from the center to any point on the circumference. The distance around the circle border is called as circumference. The area of sector is always proportional to the arc length. This Circle Calculator will be a very useful one for the middle and high grade school students do the calculations on circle's area, diameter, circumference and sector.
