As you were copying the question, did you notice the drawing alongside it ?
Well, see, that sketch is actually part of the question; anybody who wants to
try and answer it needs to see that drawing.
It will be 1/3 of the circle's circumference
It is: 72-lenghth of major arc = length of minor arc
Minor arc/Circumference = 150/360 Minor arc = 31.4*150/360 = 13.0833...
An arc length of 120 degrees is 1/3 of the circumference of a circle
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.

circumference = 2*pi*7 = 43.98229715 arc = (120/360)*43.98229715 = 14.66076572 or 14.661 units rounded to 3 dp
An arc length of 120 degrees is 1/3 of the circumference of a circle
A central angle of 120 is one third of the circle, so the arc length of 28.61 is one third of the circumference. 28.61 X 3 = 85.83

A+ 13.03^.^
Arc length = pi*r*theta/180 = 17.76 units of length.
312 cm
It is 5 cm.
length of arc/length of circumference = angle at centre/360 Rearranging the equation gives: length of arc = (angle at centre*length of circumference)/360
