The arc length is 19.68 what is the circumference of the circle?
That depends on the center angle coming from that arc. If it is 90 degrees, multiply the arc by 4, etc.
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.
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
How many degrees are there in one fourth of a circle?
Circle has 360 degrees. One fourth circle has 90 degrees
What is the relation between the arc length and angle for a sector of a circle?
A sector is the area enclosed by two radii of a circle and their intercepted arc, and the angle that is formed by these radii, is called a central angle. A central angle is measured by its intercepted arc. It has the same number of degrees as the arc it intercepts. For example, a central angle which is a right angle intercepts a 90 degrees arc; a 30 degrees central angle intercepts a 30 degrees arc, and a central angle which is a straight angle intercepts a semicircle of 180 degrees. Whereas, an inscribed angle is an angle whose vertex is on the circle and whose sides are chords. An inscribed angle is also measured by its intercepted arc. But, it has one half of the number of degrees of the arc it intercepts. For example, an inscribed angle which is a right angle intercepts a 180 degrees arc. So, we can say that an angle inscribed in a semicircle is a right angle; a 30 degrees inscribed angle intercepts a 60 degrees arc. In the same or congruent circles, congruent inscribed angles have congruent intercepted arcs.
Line HA is tangent to the circle If arc AB is 90 degrees and arc AG 20 degrees. What is the measure of angle 1?
35 degrees :)

What is the value of the degree of an angle in a semi-circle?
An angle subtended at the semicircular arc is 90 degrees.
How many Degrees is 1 arc of the circle?
That will depend on the length of the arc but an arc radian of a circle is about 57.3 degrees
Rite angle is how many degrees?
A full circle is 360 degrees, half of that, an arc, is 180. Half an arc, or a right angle, is 90 degrees. Ever heard someone say "Wow, he did a complete 180" when someone changes their mind about something? This is where it comes from. If you are in a circle and turn around to face the exact opposite side of the circle, you have turned 180 degrees. Anyway, the answer is 90 degrees.
Is a circle an arc?
an arc is a segment of a circle. If the arc subtends a full angle of 360 degrees, then the arc is a circle; but this is a special case of an arc.
What is the number of degrees in an arc of a circle?
It depends on the length of the arc because there are a total of 360 degrees in a complete circle.

A circle is didvided into n congruent arcs. What is the measure of each arc if n equals 4?
It is: 360/4 = 90 degrees
What is the circumference of a circle when the arc is 30 degrees and minor arc is 8?
The circumference of a circle is 360 degrees. The circumference of a circle is also 2*pi*radius or diameter*pi.
What is the name for 90 degrees in the circle?
If an arc of a circle is drawn so that the length of the arc is equal to the radius of the circle then the angle at the centre of the circle subtended by the arc is called one radian.Then the angle subtended by the entire circle is given by the ratio , circumference / radius = 2πr/r = 2π radians.2π radians is equivalent to 360°So, π radians = 180°and thus, π/2 radians = 90°Pi over two, or Pi divided by two radians is the name for 90° in a circle.
How do you calculate arc measures?
In degrees because an arc is part of the circumference of a circle which has a total of 360 degrees
