What is the area of a semi circle if the diameter is 16?

Answer 1

A Semicircle is half a circle, so it has half the area of the circle with diameter 16:

Area_circle = π x radius2

= π x (diameter/2)2

⇒ area_semicircle = 1/2 x π x (diameter/2)2

= 1/2 x π x (16/2)2

= 32π units2

≈ 100.53 units2

=
