A circle is a round-shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed shape, two-dimensional shape,curved shape. A few things around us that are circular in shape are a car tire, a wall clock that tells time, and a lollipop.
The center of a circle is the center point in a circle from which all the distances to the points on the circle are equal. This distance is called the radius of the circle. Here, point P is the center of the circle.
Consider the circle with center P and radius r. A circle has an interior and an exterior region. All those points for which the distance is less than the radius of a circle lie in the interior of the circle. For example points P, Q, and R lie in the interior of the circle. All those points for which the distance is greater than the radius of a circ...
Semi means half, so semicircle is half a circle. It is formed by cutting a whole circle along a line segment passing through the center of the circle. This line segmentis called the diameter of the circle.
Quarter means one-fourth. So, a quarter circle is a quarter of a circle, formed by splitting a circle into 4 equal parts or a semicircle into 2 equal parts. A quarter circle is also called a quadrant.
The Radius of a Circle: A radius is a line segment with one endpoint at the center of the circle and the other endpoint on the circle. Radius = Diameter2 Diameter of a Circle: A line segment passing through the center of a circle, and having its endpoints on the circle, is called the diameter of the circle. Diameter = 2 × radius Circumference: The ...
Area of a circle: The area of a circle is the region enclosed inside the circle. The area of a circle depends on the length of its radius. Area = πr2 Circumference: The distance around the circle is the circumference of the circle. Circumference = 2πr The value of π = 3.14 or 227
