It's 0.524 of the length of the radius.
The answer depends on the information that you have. If the arc subtends an angle of x radians in a circle with radius r cm, then the arc length is r*x cm.
The total circumference of the circle is (2 pi R) = 30 pi.The central angle of 90° is 90/360 = 1/4 of the circle.The minor arc = 30 pi/4 = 23.562 (rounded)
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.

Assuming the angle is measured in degrees, 18.84*(95/360) = 4.97166... units.

Arc length = pi*r*theta/180 = 17.76 units of length.

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.

Minor arc/Circumference = 150/360 Minor arc = 31.4*150/360 = 13.0833...
For 30 degrees arc the length = 30/360 x 2R x Pi = 1/12 x 20 x Pi = 5.236 units
You can draw exactly four of the those right-angled sectors in a circle. The definition of a sector is quoted as "the portion of a circle bounded by two radii and the included arc". The circumference of a circle = 2*pi*radius. The arc of each sector will be 0.5*pi*radius.
