Answer:
16.5 inches
Step-by-step explanation:
WE have arc length formula for a circle as
Arc length = [tex]\frac{x}{360} (2\pi r)[/tex]
where x is the central angle the arc subtends at the centre.
Here x = 135
r= 7 inches
Hence arc length
=[tex]\frac{135}{360} (2\pi )(7) =16.5"[/tex]
Hence option B
16.5 inches is right answer for arc length for a circle of radius 7 inches.
