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)

What is the length of the minor arc if the angle is 30 degrees?
It's 0.524 of the length of the radius.

How do you find the arc length of a minor arc?
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.
How do you find the length of a minor arc of a circle?
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.
Is the central angle of a minor arc an acute angle?
Not necessarily. Only if the minor arc is less than 1/4 of the circle. If the minor arc is more than 1/4 of the circle, then the central angle is obtuse.

A central angle of a circle is a right angle then what is the measure of the minor arc?
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.
How do you find the arc length of a minor arc when c equals 18.84?
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.
Is the central angle of a minor arc an acute angle?
Not necessarily. Only if the minor arc is less than 1/4 of the circle. If the minor arc is more than 1/4 of the circle, then the central angle is obtuse.
Is it true an acute angle inscribed in a circle must intercept a minor arc?
No, because there is no acute angle in a circle.
How would you find the radius of a circle when the minor arc angle is 190 degrees and the sector area is 662.89?
Another answer:- Total area of circle: 360/190 times 662.89/1 = 1256 rounded to the nearest integer Radius of the circle = square root of 1256/pi = 20 rounded to the nearest integer
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.
How do you find the minor sector in a circle?
A sector is the area of a circle defined by an angle from the center and the arc of the circle. This area equals angle theta / 360 x pi x radius squared. example: r=2 inches, theta = 60 degrees then: 60/360 x 3.141592 x 2*2 = 1/6 x 3.141592 x 4 = 2.0944 sq. in. I'm assuming by minor segment you mean the one defined by an angle less than 180 degrees. and that the remainder is the greater segment?
