A. Would a box plot, scatterplot, or histogram be most useful in helping Aurelie make a prediction? b. Considering that Aurelie is trying to predict how long it will take to complete the ride, which is the dependent variable? Make a scatterplot.

c. Use a line of best fit to predict how long it will take Aurelie to complete the charity ride. Remember that the line does not need to intersect each of the points and that the line does not need to pass through the origin to model the data.​

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)
