The question is incomplete, here is the complete question:
Given a radius of 9 inches intercepted by the central angle 60°. Estimate the length of arc 'S' to the nearest hundredth.
<u>Answer:</u> The arc length of the circle is 9.42 inches
<u>Step-by-step explanation:</u>
To calculate the length of the arc, we use the formula:
where,
S = arc length = ?
r = radius of the circle = 9 inches
= central angle = 60°
Putting values in above equation, we get:
Hence, the arc length of the circle is 9.42 inches
