You are joining the dark side and need to make your own lightsaber. The cylinder tube you will use is 30 inches long and 3 inches in diameter. You need to wrap the entire thing in red paper. How many square inches of red paper will you need? Round your answer to the nearest tenth. WhAt

296.7

i did surface area but i dont think this is right

Step-by-step explanation:

2πr^2+2πrh

2(3.14)(1.5)^2+2(3.14)(1.5)(30)

2(3.14)(2.25)+2(3.14)(45)

2(7.065)+2(141.3)

14.13+282.6=296.73

rounded to the nearest tenth: 296.7

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
