Answer: 
Step-by-step explanation:
You need to use the following formula:

Where "r" is the radius and

Assuming that that the angle
is the central angle of the arc, and knowing that the radius is 7 centimeters, you can substitute values into the formula.
Therefore, you get:

Here's the equation:
1459.75 - (359.45 + 125 + 299.35) + 375
1459.75 - 783.8 + 375
1459.75 - 408.8
