Formula for semicircle circumference

Half a portion of any circle is known as a semicircle and is formed by cutting a whole circle along the diameter. Various parameters related to a semi-circle like a diameter, area, the perimeter can be calculated using semicircle formulas.

In geometry, a semicircle is a plane figure that is formed by dividing a circle into exactly two parts. So, we can write the formulas of area and perimeter for a semicircle using the area and perimeter of a circle. In this article, you will learn how to identify a semicircle and find the area and perimeter of a semicircle with the help of formulas and solved examples. A semicircle is formed when a lining passing through the centre touches the two ends on the circle. Thus, by joining two semicircles we get a circular shape. When a circle is cut into two halves or when the circumference of a circle is divided by 2, we get a semicircular shape. In the below figure, the line AC is called the diameter of the circle.

Formula for semicircle circumference

The perimeter of a semicircle is the total length of its boundary. It is easy to calculate the perimeter of shapes that have straight edges, like in the case of a square, where all the sides can be simply added. However, the perimeter of a semicircle has a different formula since a semicircle is half of a circle, and it consists of a curved and a straight boundary. Let us learn how to calculate the perimeter of semicircle using the perimeter of semicircle formula in this lesson. The perimeter of a semicircle, which is also known as the circumference of a semicircle, is defined as the total length of its boundary. It is calculated by adding the length of the diameter and half the circumference of the original circle. The unit of the perimeter of the circle is expressed in linear units like inches, feet, meters or centimeters, etc. It can also be referred to as the perimeter of half circle. The circumference of a semicircle is another name for the perimeter of a semi circle. So, it is the length of the boundary of half of the circle's circumference and the diameter of the semi circle. Observe the following semicircle where AB is the diameter of the semicircle marked as 'd' and OM is the radius marked as 'r'. Example: Find the circumference of a semicircle whose radius is 7 units. Example 1: Find the circumference of a semicircle with a diameter of 42 inches.

Area of a Semicircle Area of a semi circle is the region enclosed by a semi circle. Semicircle is half of a circle, but the perimeter of a semicircle is not half of the perimeter of the circle.

What is more, the tool also doubles as a semicircle perimeter calculator , so inputting radius or diameter will help you find the basic features of the shape in the blink of an eye. In the article below, we provide the semicircle definition and explain how to find the perimeter and area of a semicircle. So what are you waiting for? Scroll down! However, if you're searching for a moment of inertia of a semicircle, check out our comprehensive moment of inertia calculator. A semicircle is simply half of a circle. You'll get a semicircle when you cut a circle along a diameter line — or, in other words, through the circle center.

Circles are a common shape. You see them all over: wheels on a car, Frisbees passing through the air, compact discs delivering data. These are all circles. A circle is a two-dimensional figure just like polygons and quadrilaterals. However, circles are measured differently than these other shapes. You even have to use some different terms to describe them. A circle represents a set of points, all of which are the same distance away from a fixed, middle point.
