Answer:
3183.96 ft^3
Step-by-step explanation:
let pi = 3.14
volume of a cylinder is base * height
find the base: (area of circle)
height is given
container A:
circle area = 530.66
multiply 530.66 by the height (13)
530.66 * 13 = 6898.58
container B:
circle area = 530.66
multiple 530.66 by the height (19)
530.66 * 19 = 10082.54
Find empty space:
10082.54-6898.58 = 3183.96
Answer:
The Answer is 49 - 43i Hope this helps :)
Step-by-step explanation:
If you want i can explain it.
Y=-4x+4
-4 is the gradient
So it goes downwards
+4 is the y intercept so where it crosses the y axis
Bottom right one
Remember in order to use elimination you must have opposite signs so lets make the x in equation one -2 so we can eliminate
-2(x+y=2)
-2x-2y=-4
2x+5y=16
so we get 3y=12 now divide both sides by 3 to get
y=4
so now you must plug y into one of your equations
x+4=2 so now you must get red of the 4 by subtracting four from both sides so that x=-2
so the solution is (-2,4)
