I did most of it for you-
Volume of the cone is 13.1
Volume of the cylinder is 18.9
Now, you just subtract two of the flat circular surfaces, because the two shapes are attached, therefore those parts are not surface area. And there is your answer.
Angle ADC is an inscribed angle of arc AC. So the measure of arc AC would be 46. Angle CBA is a central angle, which means it is equal to the measure of arc AC. So the answer is 46. Hope this helps!
The answers are in the photo
Price of a cone after tax = 14.58/6 = 2.43
Price before tax = 2.43 - 0.17 = 2.26
In short, Your Answer would be $2.26
Hope this helps!
