A mathematical arc is any segment of the circumference of a circle. It is normally expressed in degrees, referring to the angle between the two lines drawn from either end of the arc to the center of the circle. Therefore, a 900 arc is 1/4 of the circle's circumference and a 1800 arc is half the circumference.

the fraction of the circle covered by the arc

angle of arc/ angle of circle (360°) = length of the arc/ total circumference (2 pi* radius) so you just have to find r then so: angle of arc/ angle of circle (360°) *2pi = length of the arc/ radius radius= ength of the arc/ angle of arc/ angle of circle (360°) *2pi not that hard ;)

A piece of the circumference of a circle is called an arc A piece of the area of a circle bounded by an arc and two radii is called A sector. A piece of the area of a circle bounded by an arc and a chord is called a segment

The angle measure is: 90.01 degrees

Half of the circle is an arc

An arc. The arc covering less than half the circumference is called a minor arc; the arc covering more than half is called a major arc.

Half the circumference of a circle has an arc of 180 degrees

It is half the circumference of a circle that has an arc of 180 degrees

Answer this question… half

The only diameter would be a line segment connecting the end points of the half-circle arc.

A half circle, seriously. Go to www.google.com and click images then type arc!

Nope, a half of a diameter is the radius of a circle(: hope that helped!

If the arc is circular, such a figure is a semicircle or half circle.
