How many degrees are in the arc of a circle?
A circle contains 360 degrees. Draw a circle, add a radius to any point on it, and then rotate the radius completely around. After it has returned to the point it initially intersected the curve, the radius will have rotated through 360 degrees.(another explanation, maybe no better.)A complete circle measures 360 degrees, so a half-circle is 180 degrees, a quarter-circle is 90 degrees and so forth. Another way to look at it is in terms of the central angle formed by the radii drawn from each endpoint of the arc - the measure of the arc in degrees is the same as the measure of this central angle in degrees.
What fraction of a circle is 270 degrees?
1 / 6
What is the degree measure of a circle?
A circle is 360 degrees if that's what you're asking.
What angle measure does a semicircle have?
A semi-circle, half a circle, by definition is 180 degrees, half of a rotation. A whole circle has a whole rotation, which is 360 degrees.
What is the measure of the angle formed by two tangents drawn to a circle from an external point if they intersect a major arc whose measure is 230?
-- The major arc = 230 degrees-- The minor arc ... the arc between the tangents ... is (360 - 230) = 130 degrees.-- The line from the vertex of the angle to the center of the circle bisects the arc,so the angle between that line and the radius to each tangent is 65 degrees.-- The radius to each tangent is perpendicular to the tangent. So the radius, the tangent,and the line from the vertex to the center of the circle is a right triangle.-- In the right triangle, there's 90 degrees where the radius meets the tangent, and65 degrees at the center of the circle. That leaves 25 degrees for the angle at thevertex.-- With another 25 degrees for the right triangle formed by the other tangent,the total angle formed by the two tangents is 50 degrees.
What is a circle called if it measures 180 degrees?
How can a circle measure 180 degrees? Circles don't have any angles!
When finding the answer to a y value in a parallelogram is it degrees or radians or feet?
degrees measures angles. radians measures angles in the center of a circle. feet measures distance.
The measure from the center of a circle to its edge?
The measure from the center of a circle to its edge is the radius.
If An ARC measures 120 degrees what is the length of the radius of the circle?
The radius of a circle has no bearing on the angular measure of the arc: the radius can have any positive value.
A angle has measure of 180?
An angle with a measure of 180 degrees will look like a straight line with the vertex being a point in the center. Since a complete circle is 360 degrees, opening an angle to 180 degrees traces out exactly half a circle.
What measures the distance across the center of a circle?
The circle's diameter
What percent of a circle graph measures 18 degrees?
18 degrees is 5% on a circle graph.
If w is the center of the circle and XZ measures 96 what is the measure of XZY?

What does circumference measure?
The circumference of a circle measures the distance around the circle.
A pizza divided into six equal pieces what is angle measure of each slice?
To find the angle measure of each slice of a pizza divided into six equal pieces, you divide the total degrees of a circle (360 degrees) by the number of slices. Thus, each slice measures 360 degrees ÷ 6 = 60 degrees. Therefore, the angle measure of each slice is 60 degrees.
What is used to measure a circle?
The most commonly used measure of a circle is its radius, which is the distance from the center of the circle to any point on its circumference. The radius is generally represented by the letter "r". Other measures of a circle include its diameter (the distance across the circle passing through its center) and its circumference (the distance around the circle).
Find the area of the sector when the sector measures 10 degrees and the diameter of the circle is 12?
For a circle where sector measures 10 degrees and the diameter of the circle is 12: Sector area = 3.142 square units.
