A random sample of 318 students from a large college were asked if they were planning to visit family during Thanksgiving break. Based on this random sample, a 99% confidence interval for the proportion of all students at this college who plan to visit family during Thanksgiving break is 0.78 to 0.98. Which of the following is a correct interpretation of the confidence level?
a. If a random sample of students from this college is selected and a 99% confidence interval is constructed, there is a 99% chance that the true proportion of all students at this college who plan to visit family during Thanksgiving break is between 0.78 and 0.98
b. If a random sample of students from this college is selected and a 99% confidence interval is constructed, there is a 99% chance that the true proportion of all students at this college who plan to visit family during Thanksgiving break is between 0.78 and 0.98.
c. If many random samples of students from this college is selected and a 99% confidence interval is constructed using each sample, about 99% of those intervals would capture the true proportion of all students at this college who plan to visit family during Thanksgiving break.
d. If many random samples of students from this college is selected and a 99% confidence interval is constructed using each sample, about 99% of those intervals would capture the sample proportion of all students at this college who plan to visit family during Thanksgiving break.

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)
