A standard oil drum is a cylinder with a height of 35 inches, and a lateral surface
area of 2,637.6 square inches.
35 in.
Which of the following is the closest to
the radius of the drum in inches? (8.1A,
8.1B, 8.10, 8.10, 8.1F)

Use a calculator to verify that σ(x) = 62, σ(x2) = 1034, σ(y) = 644, σ(y2) = 93,438, and σ(x y) = 9,622. compute r. (enter a number. round your answer to three decimal places.) as x increases from 3 to 22 months, does the value of r imply that y should tend to increase or decrease? explain your answer. given our value of r, y should tend to increase as x increases. given our value of r, we can not draw any conclusions for the behavior of y as x increases. given our value of r, y should tend to remain constant as x increases. given our value of r, y should tend to decrease as x increases.
