What is arc in math mean?
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.
To find arc length what do you need to multiply a circle's circumference by?
the fraction of the circle covered by the arc
What is a piece of a circle called?
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
If the arc on a particular circle has an arc length of 12 inches and the circumference of the circle is 48 inches what is the angle measure of the arc?
The angle measure is: 90.01 degrees
What is the arc in a circle that is 90 degrees?
To find the arc length, you also need to know the radius (or diameter) of the arc. The arc length is then found by finding the circumference of the full circle (2xPIxradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
