Guided Practice The expression πr2hpi r squared h represents the volume of a cylinder, where r is the radius and h is the height. Suppose you want to see how the volume is impacted when you double the height. Which expression represents the volume of the cylinder with a height that is twice the length of the original length?

A.
π(2r)2hpi left parenthesis 2 r right parenthesis squared h

B.
(2π)r2(2h)left parenthesis 2 pi right parenthesis r squared left parenthesis 2 h right parenthesis

C.
(πr2h)2left parenthesis pi r squared h right parenthesis squared

D.
πr2(2h)pi r squared left parenthesis 2 h right parenthesis

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
