Math Problem Statement
Solution
The problem in the image asks to "Find the Arc Length" given the following information:
- inches (radius)
- radians (central angle)
Formula for Arc Length:
The formula to find the arc length of a circle is: where:
- is the radius of the circle,
- is the central angle in radians.
Substituting the given values:
So, the arc length is inches, which is approximately inches.
