Q:

# What is center of dilation in mathematics?

A:

In mathematics, the term "center of dilation" refers to a constant point on a surface from which all other points are either enlarged or compressed. The center of dilation and the scale factor comprise the two properties of a dilation.

A dilation is a type of transformation of a two-dimensional geometric figure that yields an image, which is similar in form to the initial object but varies in size. The scale factor determines the degree or amount to which the object is increased or decreased. The origin of a coordinate plane with the points x = 0 and y = 0 is the most common center of dilation in geometry.

A circle is defined as the set of all points in a plane that are the same distance from another point, which is called the center of the circle. When these points are connected, they form a closed curve. The equation for a circle on the Cartesian coordinate plane is x squared plus y squared equals r squared, where r is the radius of the circle.

The length of an arc of a circle is obtained by using the formula L=?r?/180, where L is the length of the minor arc of the circle, r is the radius of the circle and ? is the angle made by the arc at the center of the circle.

To calculate the diameter of a circle, multiply the radius of the circle by 2. Diameter is the measure of the length of a straight line that passes through the center of a circle, touching the circumference or surface at two opposite end points. Radius is the distance from the center of the circle to any point on the circumference.

The center of a circle is simply referred to as the center. However, it is often given the distinction of "0" in drawings and formulas of circles. The center of a circle is defined as the point from which all points of the circumference are equidistant.
