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 ...
