<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.

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




Hence, the length of arc AB is terms of π is 3π
To find what she saved you need to subtract
500-325= 175
