In my opinion I think that you have to multiply 13.55 by 8 ounces to find how much she needs to pay.
The area of the entire sector of DEF = 60 / 360 * PI * radius^2
sector area = 1 / 6 * 3.14159265... * 20^2
sector area =

segment area = sector area - triangle DEF Area
triangle DEF Area = (1/2) * 20 * sine 60 * 20
triangle DEF Area = (1/2) * 0.86603 * 400
triangle DEF Area = <span><span><span>(1/2) * 346.412

12 - 1/6 *12 - 2/3 * 12
12 - 2-8
