Semicircle area formula. It has 180º arc. Hi, am Murali a Mathematics blogger. Learn and know the formula by which we can find the area of semi circle. Where r is the radius; a is the arc angle also known as the central angle. By this, we can conclude that any one of the formulae out of 2 i.e. In semi circle, Semi meaning is half so half of circle will be a semi circle. Solution: 1.) Knowing the semicircle definition - half of a circle - we can easily write the semicircle area formula using the well-known circle area, πr² : Area semicircle = Area circle / 2 = πr² / 2. (adsbygoogle = window.adsbygoogle || []).push({}); Help With Math Similarly, for a semicircle, the moment of inertia of the x-axis is equal to the y-axis. The diameter of the circle divides the circle into two equal semicircles. Since a semicircle is just half of a circle, the area of a semicircle is shown through the formula A = πr2 2. You find the area of a semicircle by plugging the given radius of the semicircle into the area of a semicircle formula. A = \frac { 1 }{ 2 } × π × { r }^{ 2 }   where π = \frac { 22 }{ 7 } (or) we can also take π as 3.14 and “r” is the radius of the given semi circle.
