Area of a Circle:The Area of a Circle is the space occupied by the circle in a two-dimensional plane. A circle is a critical geometric figure that is present across many areas such as construction, engineering, and many more. Solving problems related to circles in Geometry requires us to ...
Thearea of a circlehaving a radius ‘r’ (The distance from the centre to a point on the boundary) is given by πr2where π = $\frac{22}{7}$ or 3.14 (approx.) For example, suppose we have a circle that has a radius of 7 cm as shown in the figure below. Its area is given...
A circle can contain a rectangle with all its vertex touching the circumference; it is called a cyclic rectangle. Thesquareis a special type of rectangle whose length and width are the same. Hence, the area of a square is given by multiplying the length of each side by itself. ...

The π is a mathematical constant known asPi. π is the ratio of the circumference orperimeterof any circle to its diameter. Its approximate value is 3.14159. If I double the radius of a sphere, what happens to the surface area?
Within geometry, an ellipse is a shape that is an oval or an elongated circle in which its axes are symmetrical to one another. Additionally, an ellipse can be defined as a shape in which the sum of the distance of its focal points toward its curved edge is always constant. This image...
A circle is a round shaped figure that has no corners or edges. In geometry, a circle can be defined as a closed, two-dimensional curved shape. What is area example? Area is the amount of space within the perimeter of a 2D shape. It is measured in square units, like cm², m²...

A circle is defined by a point, known as the centre, and a constant distance from this point, known as the radius. The total length of the boundary of the circle is referred to as the circumference. A significant aspect of circles in geometry is the area they enclose. In this article,...
The area of a circle is:π (Pi) times the Radius squared:A = π r2 or, when you know the Diameter:A = (π/4) × D2 or, when you know the Circumference:A = C2 / 4πExample: What is the area of a circle with radius of 3 m ? Radius = r = 3 Area= π r2 = π× ...
