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:

Answer:
independent is the y value or the value that changes at a steady rate no matter what, the dependent variable or x is the variable that is subject to change and is dependent on the y value to find a pattern
