What else can I help you with?
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.
Does a minor arc measure exactly 180 degrees?
No. Given two points on a circle, the minor arc is the shortest arc linking them. The major arc is the longest.
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.
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.
What is the length of the minor arc if the angle in the circle is 90 and the radius of the circle is 15?
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)
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.
Does a minor arc measure exactly 180 degrees?
No. Given two points on a circle, the minor arc is the shortest arc linking them. The major arc is the longest.
What is the arc length of minor arc 120 degrees?
It will be 1/3 of the circle's circumference
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.
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.
Part of the circumference of a circle is called?
An arc. The arc covering less than half the circumference is called a minor arc; the arc covering more than half is called a major arc.
What will a minor arc measure?
Part of the circumference of a circle less than 180 degrees
The measure of a major arc is greater than 180?
A circle subtends 360° . Therefore. if the angle subtended at the centre of a circle by an arc is greater than 180° then this is the major arc. By comparison, the minor arc will subtend an angle less than 180°
What is the length of the minor arc if the angle in the circle is 90 and the radius of the circle is 15?
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 minor arc has a measure of 120 degrees what is the measure of the major arc?
A whole circle is 360 deg so the major arc is 360-120 = 240 degrees.
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.
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.
