Area of a Sector of Circle = (θ/360º) ×πr2, where, θ is the sector angle subtended by the arc at the center, in degrees, and 'r' is the radius of the circle. Area of a Sector of Circle = 1/2 × r2θ, where, θ is the sector angle subtended by the arc at the ce...
- 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...
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...
Apart from those simple, real-life examples, the sector area formula may be handy in geometry, e.g., for finding the surface area of a cone. FAQs What is the sector of a circle? The sector of a circle is a slice of a circle, bound by two radiuses and an arc of the circumference...
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?
