find the circumferance as if it was a whole circle but when you get the answer divide it by 2
It's half of the area of the whole circle...

It is the same as the radius of the whole circle.
A part of a circle is called an arc. The defined values for a circle are: radius, diameter, chord, area, circumference, and the arcs. There is the circumfrence, semi circle, arc, diameter,chord,segment,radius,quaderent
The length (circumference) of the curved part of a semi-circle is pi times the radius (pi*R). If the diameter is given, then the semi-circle length is 1/2 (pi * x D) because the radius is 1/2 of the diameter.(There are 2pi radians in a full circle.)A closed shape formed from a semi-circle has a perimeter P = D + (pi * D / 2)(diameter plus the curved part)
It is a semi circle
Being half of the circumference of a circle, a semi circle has one side
It is half of a circle; the circle's radius (and that of the semicircle) is 10 cm.
It is a semicircle.
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.
