circumference = 2*pi*7 = 43.98229715 arc = (120/360)*43.98229715 = 14.66076572 or 14.661 units rounded to 3 dp
Length of arc = pi*radius*angle/180 = 10.47 units (to 2 dp)
The radius of a circle has no bearing on the angular measure of the arc: the radius can have any positive value.
3.34 units
A whole circle is 360 deg so the major arc is 360-120 = 240 degrees.
Arc length = pi*r*theta/180 = 17.76 units of length.

It will be 1/3 of the circle's circumference
An arc length of 120 degrees is 1/3 of the circumference of a circle
circumference of the circle = 2*pi*10 = 20pi units of measurement length of arc = (120/360)*20pi = 20.944 units (rounded to 3 decimal places)
The length of an arc, with an angle in degrees, is equal to (pi x r x θ)/180.In this case, it is (pi x 120 x 10)/180, which is (20pi)/3 or about 20.944.This answer is not right for A+
