The components of the circle are: Radius: It is the distance from the outside edge of the circle to the center point of the circle. It is the primary component of a circle that helps in calculation. Diameter: A parallel line runs from one side of the circle to the other, passing thro...
- Circle: The area of a circle is calculated using the formula: Area = π x radius^2, where π is a constant approximately equal to 3.14159. - Parallelogram: The area of a parallelogram is calculated by multiplying its base by its height. Applications of Area The concept of area has num...
A shape is defined as a figure enclosed by a boundary. We see uncountable objects around us in shapes such as square, rectangle, circle etc. Now, what is this area of shape? Let’s dive deeper into the concept.The area of shape is the space enclosed within the perimeter or the ...
Despite this, a regular shape such as a circle is not considered a polygon since it lacks straight lines. There are plenty of examples of regular shapes in real life, such as a stop sign, which has eight equal sides and angles, and the tires of a bicycle. Regular shapes in real life...
A circle can contain a rectangle with all its vertex touching the circumference; it is called a cyclic rectangle. The square is 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.Solved...

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?
The length of the diagonals are The radius of the incircle is equal to half of the side of the square. Area of Square: Formulas To calculate the area of a square, we must understand that it is equal to the sides of the square. It is measured in square meters. ...
What is the Formula for Area of Sector of Circle? The two main formulas that are used to find thearea of a sectorare: Area of a Sector of Circle = (θ/360º) ×πr2, where, θ is the angle subtended at the center, given indegrees, and 'r' is the radius of the circle. ...
