## Arc Length Calculation

Find arc length in terms of π and to the hundredths place. Find degree measurements to the nearest degree. Find all other measures to the nearest hundredths place.

### Find the length of \( \overset{\frown}{AB} \).

Below are three diagrams for which you need to calculate the arc length of \( \overset{\frown}{AB} \).

### Diagram 1:
- A circle is shown with center \( Q \).
- The point \( A \) is on the outer circumference.
- Another point \( B \) is on the circumference such that \( \angle AQB \) is a right angle (90 degrees).
- The radius \( QA \) measures 7 inches.

### Diagram 2:
- A circle is shown with center \( Q \).
- The point \( A \) is on the outer circumference.
- Another point \( B \) is on the circumference such that \( \angle AQB \) is 120 degrees.
- The radius \( QA \) measures 6 feet.

### Diagram 3:
- A circle is shown with center \( Q \).
- The point \( A \) is on the outer circumference.
- Another point \( B \) is on the circumference such that \( \angle AQB \) is 45 degrees.
- The radius \( QA \) measures 12 centimeters.
