The length measure of the arc could be a little bit bigger than √[(2)242] or 33.94 cm. Let see...
Since the degree of the arc is 90⁰, its length measure would be 1/4 of the circumference of the circle with radius 24 cm.
C = 2(pi)(r) = 2(3.142)(24 cm) = 150.8 cm
1/4 of 150.8 cm = 150.8/4 cm = 37.7 cm
Thus the arc length is about 37.7 cm.
The total circumference is (arc length) times (360) divided by (the angle degrees)
Find the circumference of the whole circle and then multiply that length by 95/360.
2*pi*r/Arc length = 360/Degreesince both are a ratio of the whole circle to the arc.Simplifying,r = 360*Arc Length/(2*pi*Degree) = 180*Arc Length/(pi*Degree)
To find the arc length of a circle given a central angle, you can use the formula: Arc Length = (θ/360) × (2πr), where θ is the central angle in degrees and r is the radius of the circle. For a circle with a radius of 60 inches and a central angle of 35 degrees, the arc length would be: Arc Length = (35/360) × (2π × 60) ≈ 36.7 inches.
The length of a chord = pi*r*x/180 where x is the angle subtended. = pi*5*80/180 = 6.98 cm
say a circle's degree is 360. and cut it in half to make an ark. that would 180 degrees?
The total circumference is (arc length) times (360) divided by (the angle degrees)
-- Circumference of the circle = (pi) x (radius) -- length of the intercepted arc/circumference = degree measure of the central angle/360 degrees
An arc can be measured either in degree or in unit length. An arc is a portion of the circumference of the circle which is determined by the size of its corresponding central angle. We create a proportion that compares the arc to the whole circle first in degree measure and then in unit length. (measure of central angle/360 degrees) = (arc length/circumference) arc length = (measure of central angle/360 degrees)(circumference) But, maybe the angle that determines the arc in your problem is not a central angle. In such a case, find the arc measure in degree, and then write the proportion to find the arc length.
To find the fraction of a 360 degree circle that is 30 degrees, you would divide the angle measurement by the total angle of the circle. So, 30 degrees divided by 360 degrees equals 1/12. Therefore, 30 degrees is 1/12 of a 360 degree circle.
An arc length of 120 degrees is 1/3 of the circumference of a circle
Find the circumference of the whole circle and then multiply that length by 95/360.
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).
Divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
It depends on what information you have: the radius and the area of the sector or the length of the arc.
You can find the Antarctic Circle at about 66.5628° S. Because the earth wobbles, the circle moves with it.
To find the length of an arc in a circle, you can use the formula L = (θ/360) x 2πr, where L is the length of the arc, θ is the central angle in degrees, and r is the radius of the circle. In this case, with a central angle of 150 degrees, the formula becomes L = (150/360) x 2πr = (5/12) x 2πr. Therefore, the length of the arc would be (5/12) times the circumference of the circle with radius r.
