We'll be analyzing the surface area of a round cylinder - in other words the amount of material needed to "make a can". A cylinder (round can) has a circular base and a circular top with vertical sides in between. Let r be the radius of the top of the can and let h be the height. The surface area of the cylinder, A, is A = 2mr2 + 2rrh (it's two circles for the top and bottom plus a rolled up rectangle for the side). r = radius Areas = 1 12 h = height Area = h(2atr) Circumference 2ntr Save Quit & Save Previous Unit Item Next Unit Item Previous Page Next Page Type here to search O w P 3 10:53 AM ? 75OF ~ 06 1') 7/8/2021 E1M S m Southern New Hampshire Univer X Course Hero X B 2-1 Discussion: Surface Area - M/ x WALT Key Shortcuts to Insert Symb x m Southern New Hampshire Univer X X C D snhu.mobius.cloud/892/2196/assignments/70677/0 88 : Apps mySNHU Login Mario stuff Homepage | NuVal 5 4th Grade Capitaliz..

Other bookmarks Reading list Circumference 2ntr Part a: Assume that the height of your cylinder is 4 inches. Consider A as a function of r, so we can write that as A (r) = 2 mr2 + 8 mr. What is the domain of A (r)? In other words, for which values of r is A (r) defined? Part b: Continue to assume that the height of your cylinder is 4 inches. Write the radius r as a function of A. This is the inverse function to A (r), i.e to turn A as a function of r into. r as a function of A. r (A) = 2* Tir +8*Pi Hints: . To calculate an inverse function, you need to solve for r. Here you would start with A = 2 mr + 8 mr. This equation is the same as 2 mr + 8 ar - A =0 which is a quadratic equation in the variable r, and you can solve that using the quadratic formula. . If you want to type in 3 7+1 x+1 in Mobius, in text mode you can type in (3*pitl)/(x+1). There is more information in the Introduction to Mobius unit.

Part c: If the surface area is 300 square inches, then what is the rardius r? In other words, evaluate r (300). Round your answer to 2 decimal places. Hint: To compute a numeric square root such as v17.3, you could . Use a spreadsheet such as Microsoft Excel or OpenOffice Calc and type in =sqrt(17.3) . Use a browser to connect to the Internet and type in sqrt(17.3) into a search field . Use a calculator The radius is Number inches if the surface area is 300 square inches.
