Step-by-step explanation:
See attachment for correct format of question.
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](/tpl/images/0710/7488/8f743.png)
Substitute 20 for θ and 27 for r
![Length = \frac{20}{360} * 2\pi *27](/tpl/images/0710/7488/a7ec6.png)
![Length = \frac{20 * 2\pi * 27}{360}](/tpl/images/0710/7488/8b148.png)
![Length = \frac{1080 \pi}{360}](/tpl/images/0710/7488/6bea6.png)
![Length = 3\pi](/tpl/images/0710/7488/9f444.png)
Hence, the length of arc AB is terms of π is 3π
