Complete the derivation of the formula for a cylinder
whose height is equal to its radius.
Suppose the height of a cylinder is equal to its radius.
The cylinder can fit inside a square prism, as shown
below.
The cross-sectional areas are still the same and the ratio
of the area of the circle to the area of the square is still I
The prism's volume is the area of the base,
times the height,
4
Since the ratio of the areas is , then the volume of the
times the volume of the prism.
cylinder is
r
2r
V = (413), or

Which of the following is the inverse of y = 3∧x y = 1/3∧x y = ㏒3x y = (1/3) ∧x y = ㏒ 1/3∧x

The weight v of an object on venus varies directly with its weight e on earth. a person weighing 120 lb on earth would weigh 106 lb on venus. how much would a person weighing 150 lb on earth weigh on venus?

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
