A classroom with an area of 500 square feet has room for 30 students. A classroom with an area of 1,500 square feet has room for 80 students. A. Write the relationship of students to square feet, for the smaller classroom, as a ratio and as a fraction in its simplest terms.
B. Write the relationship of students to square feet, for the larger classroom, as a ratio and as a fraction in its simplest terms.
C. The original ratios of students to square feet in the two classrooms are not equal. How many students can the larger classroom hold to make its ratio of students to square feet equal to that of the smaller classroom?

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)
