Aglass has circular cross sections that taper (linearly) from a radius of 4 cm at the top of the glass to a radius of 3 cm at the bottom. the glass is 17 cm high and full of orange juice. how much work is required to drink all the juice through a straw if your mouth is 7 cm above the top of the glass? use 1000 kg divided by m cubed for the density of orange juice and 9.8 m divided by s squared for the acceleration due to gravity. find the cross-sectional area a(y) of a horizontal slice at y. use the center of the bottom of the glass as the origin in your coordinate system.
