It does not measure anything. It is a two dimentional figure equivelent to half of a circle.
to find the area of a semi circle measure the length of the straight edge, divide by 2, square it and multiply by pi. This will give you the area of the circle. To get the area of the semi-circle divide your answer by 2

Circle. That is the opposite of semi circle.
The radius of a semi-circle is the same as the radius of the circle that was cut in half. The radius of a circle is the distance from the center of the circle to any point on the circle. That's the same as 1/2 of the diameter. It's easy to measure it on a semi-circle, because you don't even need to determine where the center is. The diameter is just the length of the flat side, and the radius is half of that.
The semi-circle ruler is commonly known as a protractor. A protractor is a geometric tool used to measure and draw angles. It typically has a half-circle shape with degree markings along the curved edge.
