Solution: In the question, we have given the circumference of the circle and we have to calculate the radius of the circle. Therefore, Circumference of the Circle(C) = 18.85 cmĮxample 2: Find the radius of the circle having C = 100 cm. Solution: In the question, we have given the diameter of the circle, we can find the radius of the circle by putting r = d/2 in the formula of Circumference of Circle. Circumference Formula of Semicircle = (πr 2r)Ĭircumference of Circle Formula: Solved ExamplesĮxample 1: What is the circumference of the circle with a diameter 6 cm? Let us know the Circumference Formula of Semicircle. If we are dividing the circle into equal parts then the circumference of the circle will also be divided equally. it is formed when we divide the circle into two equal parts. Semicircle is the half of the circle i.e. If the diameter of a circle is given then also we can find the circumference by putting r = d/2 in the same formula given above.Ĭircumference Formula of Circle(c) = 2π* (d/2) Circumference Formula of Circle(c) =πd We know that the radius of the circle is half of the diameter of the circle. Suppose the radius of the circle is not given the how the circumference of a circle will be calculated? Where r is the radius of the circle and c is the circumference of the circle. Radius: The radius of a circle is the distance between the circle’s center and any point along its perimeter.īuy Online JEE Main/Advanced 2022 Course Circumference Formula of Circle(c) = 2πr The three most important elements of a circle are :Ĭenter: The center is located equidistance from every other point on the circle.ĭiameter: The diameter of a circle is the distance from the center to the circumference. Let’s take a look at the components that make up circumference. The circumference of a circle is the length of its periphery. To get notification of related topics, do bookmark this page, here we post some interesting and complex concepts in laymen’s language so that students can understand better.īuy Online NEET 2022 Course Circumference of Circle Formula In this article, we will discuss the circumference of 2-dimensional shapes. These all shapes are called 3-dimensional shapes. We have 3-dimensional shapes too which are cone, sphere, cylinder, cube. These all shapes are called 2-dimensional shapes. We have many geometrical shapes in maths such as triangle, square, circle. Every shape has a circumference, the outer periphery that surrounds the shape. The circumference is the outer boundary of any shape and circumference is also known as the perimeter. FAQs on Circumference of Circle FormulaĬircumference of Circle Meaning
