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)
The length of a chord = pi*r*x/180 where x is the angle subtended. = pi*5*80/180 = 6.98 cm
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.
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.
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.
Use the information you have to find it. -- divide the length of the arc by the total circumference of the circle, or -- divide the central angle of the arc by 360 degrees (a full circle)
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)
