Find the length of AB. Leave
vovikov84 [41]

Answer:

<em>AB = 3π</em>

Step-by-step explanation:

<em>See attachment for correct format of question.</em>

Given

From the attachment, we have that

θ = 20°

Radius, r = 27

Required

Find length of AB

AB is an arc and it's length can be calculated using arc length formula.

Length = \frac{\theta}{360} * 2\pi r

<em>Substitute 20 for θ and 27 for r</em>

Length = \frac{20}{360} * 2\pi *27

Length = \frac{20 * 2\pi * 27}{360}

Length = \frac{1080 \pi}{360}

Length = 3\pi

Hence, the length of arc AB is terms of π is 3π
