Step-by-step explanation:
Given
h = 5 mi
r = 6 mi
Surface Area of Cylinder =
![2\pi \: rh + 2\pi {r}^{2} \\ = 2\pi(6)(5) + 2\pi ({6}^{2}) \\ = 2\pi(30) + 2\pi(36) \\ = 60\pi + 72\pi \\ = 132\pi \\ = 414.690 {mi}^{2} (nearest \: thousandth)](https://tex.z-dn.net/?f=2%5Cpi%20%5C%3A%20rh%20%2B%202%5Cpi%20%7Br%7D%5E%7B2%7D%20%20%5C%5C%20%20%3D%202%5Cpi%286%29%285%29%20%2B%202%5Cpi%20%28%7B6%7D%5E%7B2%7D%29%20%20%5C%5C%20%20%20%3D%202%5Cpi%2830%29%20%2B%202%5Cpi%2836%29%20%5C%5C%20%20%3D%2060%5Cpi%20%2B%2072%5Cpi%20%5C%5C%20%20%3D%20132%5Cpi%20%5C%5C%20%20%3D%20414.690%20%7Bmi%7D%5E%7B2%7D%20%28nearest%20%5C%3A%20thousandth%29)
Dividing by a fraction is like multiplying with the inverse.
So 14 / (2/7) is the same as 14 * 7/2, which is 49
A could be 2 while B could be 3, so -2a+3b turns into -4+9, which equals 5.
From what I know you can't really solve a a single equation with two-variables so it's just a matter of trial and error.
Just try plugging in a small number like 2 for a just to try it and you get 8b^2=72.
Divide everything by 8 to isolate b and you get that b^2=9.
Square root everything and you'll find that b=3. This is just one possible combination, I'm sure there are many more but this is obviously the one that was intended to be found.
Now that we know that a=2 and b=3 just plug them into the equation.
-2(2)+3(3)=?
-4+9=?
5
Sorry about having to use this ^ symbol, the equation maker is not working.
Answer:
56 multiplied by 9 = 504
Step-by-step explanation:
55.8 rounded is 56, and 9.12 rounded is 9
Sin(D) = 24/25
tan(D) = 24/7
sin(E) = 7/25
