WebThe solid region is rotation about y-axis at x=6. So we will have a washer shape and inner radius of shell is r and outer radius is R. In this example, we will find the inner radius by the distance between the line x = 4 and the line x = 6, so r = 2. The outer radius R is the horizontal distance between the graph of y=√x and the line x = 6. WebJan 10, 2024 · The atomic weight of an element is double its, atomic number.
