Question

Find the length of the arc. A. 187π/12 ft B. 16π/3 ft C. 49π/6 ft D. 343π/12 ft

Answer 1

Answer:

$\huge \boxed{\mathrm{Option \ C}}$

Step-by-step explanation:

Length of arc formula = θ/360 × 2$\pi$r

The angle is 210 degrees.

The radius is 7 ft.

210/360 × 2$\pi$(7)

Simplify the expression.

210/360 × 14$\pi$

2940/360$\pi$

49/6$\pi$
