Question: The Storage Shed Shown To The Right Is The Shape Of A Half Cylinder Of Radius R = 4m And Length 1 = 20m. The Shed Is Filled With

The storage shed shown to the right is the shape of a half cylinder of radius 7* = 4m and length = 20m. The shed is filled with salt whose density at a point is given by f(y) = ky (measured in kg/m) where k is a constant and y is the distance of that point to the floor. (Be sure to, first, draw a slice and find an expression for its mass. In choosing how to slice this, consider the physics.) a) How do you decide to make your slices? Why? b) Draw a representative slice. What are its dimensions?
