How many lines of symmetry in a circular arc?
As long as the arc isnt a full circle, just 1, if it is a circle, infinite.
How would your find the fraction of a circle that an arc covers?
Use the information you have to find it. -- divide the length of the arc by the total circumference of the circle, or -- divide the central angle of the arc by 360 degrees (a full circle)
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
What is the length of the arc on a circle of radius r equals 5 yards intercepted by a central angle theta equals 70 degrees?
To work out the length of the arc on a circle, you need to work out the proportion of the full circle that the arc represents. This is the proportion of the circumference of the circle. The circumference of a circle is 2 times pi times radius or 2{pi}r A full circle has 360o so an arc created between 2 radii with an angle of ao between them has a length that is a/360 that of the full circle, ie length of arc = 2{pi}ra/360 Thus, for a circle of radius r=5yds and angle=72o, the length of the arc is: 2x{pi}x5x72/360 = 2x{pi}x5x1/5 = 2x{pi} ~= 6.28yds
A of a circle is a region bounded by an arc of a circle and radii to the endpoints of the arc?
sector
How many arc seconds in a full circle?
A full circle has 360 degree; each degree has 60 minutes; each minute has 60 seconds. Multiply those three numbers to get the desired answer.
How many seconds there are in a circle?
The calculation is 60 arc seconds X 60 arc minutes X 360 degrees in a full circle. So, there are 1,296,000 arc seconds in a full circle.
How many seconds of arc are in a circle?
1,296,000
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.

How many arc seconds in an arc minute?
60
How many arc minutes in a full circle?
There are 60 arcminutes in one degree. There are 360 degrees in a circle. Therefore, one full rotation is equal to 360 x 60 = 21600 arcminutes.
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).
How do you convert arc seconds to inches?
Conversion of arc seconds to inches depends on the distance that is being measured. There are 360 degrees in a circle, 60 minutes per degree and 60 seconds per minute. The circumference of a circle is PI * diameter. So 1 arc second of a 1 foot diameter circle is equal to .000029 inches. (12 * PI inches diameter divided by (360*60*60))
