James is researching earthquakes for a science report. He is trying to come up with his own scale to rank the intensity of an earthquake. He notices that the difference in the intensity of the smallest earthquake, x, and the largest earthquake, y, is a magnitude of several hundred thousand. James comes up with a scale that allows him to show these differences and is easy to use and interpret.

Name the most appropriate metric unit for each measurement like the mass of cow

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)

Meee i honestly dont know what this question talking about
