Question

In circle O below, what is the length of arc AB in radians?

Answer 1

Answer:

Length of arc = 0.628 r

Step-by-step explanation:

Given:

∠ AOB = 36°

Radius = (r)

Find:

Length of arc AB = ?

Computation:

$Length\ of \ arc = \frac{\theta}{360}2\pi r\\\\Length\ of \ arc = \frac{36}{360}(2)(\frac{22}{7} ) (r)\\\\Length\ of \ arc =0.628r$

Length of arc = 0.628 r
