Circle: Area and Perimeter Formula
Circle is the 2-D shape which has a center and drawn using equal distance from the center called the radius of the circle.
Area of Circle
The area of the circle with radius r is given by:
Area of circle = πr2
Where r is radius of circle.
Perimeter of Circle
The perimeter of the circle with radius r is given by:
Perimeter of circle = 2πr
Where r is radius of circle.
Area and Perimeter Formulas
Area and Perimeter Formulas are the fundamental formulas in Mensuration that help us calculate the area and perimeter for any geometric shape in mathematics. Area and Perimeter Formulas have equal importance in real life for various calculations like finding the area of land or finding the perimeter of land for boundaries and many more.
In this article, we will explore all the different formulas to find the Area and Perimeter of various geometric shapes such as Triangles, Squares, Rectangles, Rhombus, Parallelogram, Circle, Semicircle, and Ellipse. We will also cover the solved examples of the area and perimeter formula. Let’s start our learning on the topic of Area and Perimeter Formula.
