Verified step by step guidance1
Recall the formula for the length of an arc \(s\) in a circle, which is given by \(s = r \times \theta\), where \(r\) is the radius and \(\theta\) is the central angle in radians.
Identify the given values: the radius \(r = 10\) inches and the central angle \(\theta = 3\) radians.
Substitute the given values into the arc length formula: \(s = 10 \times 3\).
Multiply the radius by the angle to find the arc length: \(s = 30\) inches (this is the exact value before approximation).
Compare the calculated arc length with the provided options to choose the closest value.
