Since the minor arc is 30 degrees, the major arc is 330 degrees (360 - 30).
So we have:
330 degrees : arc length 10
30 degrees : arc length x
330/30 = 10/x
11/1 = 10/x
x = 10/11
x = 0.9 approximately
So the length of the minor arc is approximately 0.9 units.
To find the measure of a major arc in a circle, first determine the measure of the corresponding minor arc, which is the smaller arc connecting the same two endpoints. The measure of the major arc is then calculated by subtracting the measure of the minor arc from 360 degrees. For example, if the minor arc measures 120 degrees, the major arc would measure 360 - 120 = 240 degrees.
To find major arcs in a circle, first identify the endpoints of the arc on the circumference. Measure the angle subtended by the endpoints at the center of the circle; if the angle is greater than 180 degrees, the arc is a major arc. Alternatively, you can calculate the minor arc (the shorter arc between the two points) and subtract its length from the total circumference to find the length of the major arc. Major arcs are typically labeled with three points, including the endpoints and a point on the arc itself.
To find the arc length of a minor arc, you can use the formula: ( L = \frac{\theta}{360} \times 2\pi r ), where ( L ) is the arc length, ( \theta ) is the central angle in degrees, and ( r ) is the radius. For a minor arc with a central angle of 120 degrees and a radius of 8, substitute the values into the formula: ( L = \frac{120}{360} \times 2\pi \times 8 ). This simplifies to ( L = \frac{1}{3} \times 16\pi ), resulting in an arc length of approximately ( 16.76 ) units.
If the radius of the circle is r units and the angle subtended by the arc at the centre is x radians, then the length of the arc is r*x units. If you are still working with angles measured in degrees, then the answer is r*pi*y/180 where the angle is y degrees. If r and x (or y) are not available, or cannot be deduced, then you cannot find the length of the arc.
"That would be A minor. Go a minor third below the tonic of the major scale to find the relative minor." Technically, there is no relative harmonic major to the key of C Major. The relative minor scale of C Major would the natural minor scale of A. A harmonic minor scale raises the 7th note of the scale a half step, giving us G#, which is not in the key of C Major.

To find the relative major of a minor key, you can go up three half steps from the minor key. For example, the relative major of A minor is C major.
To find the parallel minor of a major key, you simply need to go down three half steps from the major key. For example, the parallel minor of C major is A minor.

To find the relative minor of a major key, you can count down three half steps from the major key's root note. This will give you the relative minor key.
I'm assuming that "c" is short for "circumference". The length of an arc is (circumference)*(360/angle). So the length of an arc in a circle with circumference length of 18.84 is 6782.4/angle, where the angle is measured in degrees.
To find the arc length of a minor arc, you can use the formula: ( L = \frac{\theta}{360} \times 2\pi r ), where ( L ) is the arc length, ( \theta ) is the central angle in degrees, and ( r ) is the radius. For a minor arc with a central angle of 120 degrees and a radius of 8, substitute the values into the formula: ( L = \frac{120}{360} \times 2\pi \times 8 ). This simplifies to ( L = \frac{1}{3} \times 16\pi ), resulting in an arc length of approximately ( 16.76 ) units.
Count up a sixth from the major (C) to find the minor (A).
If the radius of the circle is r units and the angle subtended by the arc at the centre is x radians, then the length of the arc is r*x units. If you are still working with angles measured in degrees, then the answer is r*pi*y/180 where the angle is y degrees. If r and x (or y) are not available, or cannot be deduced, then you cannot find the length of the arc.
