Answer:
Step-by-step explanation:
Recall that the formula for the length of an arc of circumference is given by the formula:
where 
is the radian form of central angle subtended , and R is the radius of the circumference. What is important is to have the angle given in radians for this formula to be valid.
In our case, the angle ( 
) is already in radians, so we can apply the formula directly:
The answer to the question is 12.875
1) 1/3x - 2/3 = -18
2) 1/3x - 2/3 + 2/3 = -18 + 2/3
3) 1/3x = -54/3 + 2/3
4) 1/3x = -52/3
5) (1/3x) divided by 1/3 = -52/3 divided by 1/3
6) x = -52/3 x 3/1
7) x = -52
