Angle Inscribed in a Semicircle The angle inscribed in a semi circle is always 90-degree no matter the radius of the semi circle. In the figure above, AC is the diameter of the semicircle. The inscribed angle of the semi circle is formed by drawing a line from each end of the diameter...
Since a semicircle is half of a circle, the area of a semicircle is half of a circle. So, the formula to find the area of a semicircle is pi times radius squared divided by 2, or pi times diameter squared divided by 8: Area of a semicircle formula...
Semicircle area formula Knowing the semicircle definition – half of a circle – we can easily write the semicircle area formula using the well-known circle area, π⋅r2π⋅r2: Asemicircle=Acircle2=π⋅r22Asemicircle=2Acircle=2π⋅r2 The area of a semicircle is just half of the ...
The figure given below represents the sectors in acircle. The shaded region shows the area of the sector OAPB. Here, ∠AOB is theangleof the sector. It should be noted that the unshaded region is also a sector of the circle. So, the shaded region is thearea of the minor sectorand t...
