Question

Find the length of each arc. Round to the nearest tenth.

Answer 1

Answer:

arc ≈ 5.5 units

Step-by-step explanation:

The arc of the circle is calculated as

arc = circumference of circle × fraction of circle

     = 2πr × $\frac{\frac{\pi }{2} }{2\pi }$ ( r is the radius )

    = 2π × 3.5 × $\frac{1}{4}$

    = $\frac{7\pi }{4}$

    ≈ 5.5 ( to the nearest tenth )
