Semi-circle. (2D) Hemi-sphere (3D)
hemisphere
There is no such thing as a 1 sided shape nor a two sided shape.
The radius is half of the diameter of a circle.
The area of any circle is (pi) x (radius)2 .The area of half the circle is just half of that number.
Semicircle is HALF of a circle!
a half circle? a half? semi circle? half sphere?
We call it a "semi-circle"
Assume the shape is half circle. The area of the circle is: A = πr² where r is the radius Since the semi circle has half the area of the circle, we obtain: A = πr²/2
A semi-circle
The half of a diameter of a circle is known as a radius.
hemisphere
A semicircle.
the shape is a sphere!
a semi circle? common sense
a line or half a circle?
it is similar to a half circle but it the half circle is connected from end to end and it is rotated 90 degrees to the left and or right
quarter Moon if its half of a sphere then its half moon
