Circle Area

Area is a numerical characteristic of a two-dimensional (flat or curved) geometric figure, informally speaking, showing the size of this figure. Historically, the calculation of the area was called quadrature. A figure having an area is called quadratic. Find the area of more than 22 shapes (triangle, square, pentagon, etc.) using our amazing calculator.

Circle — is a part of a plane lying inside a circle. In other words, this is the geometrical location of the points of the plane, the distance from which to a given point, called the center of the circle, does not exceed a given non-negative number. The number is called the radius of this circle. If the radius is zero, then the circle degenerates to a point.
