Answer:
<h2> 8in</h2>
Step-by-step explanation:
the given formula in the question is not correct
here is the correct formula
S. A. =2πr^2 +2πrh
given that S.A=207.24
radius r= 3in
207.24=2*3.142*(3)^2 +2*3.142*(3)h
207.24=56.556 +18.852h
207.24-56.556=18.852h
150.684=18.852h
h=150.684/18.852
h=7.99
Approximately the height is 8in
Answer:
3/4
Step-by-step explanation:
8x = 6
x = other number = 6/8 = 3/4
Draw anything and colour the whole thing in.
If we multiply the bottom equation by 2 and move x to the right, it becomes:
4y = 2x-38
Now we can substitute it for the 4y in the top equation:
3x + (2x-38) = -23 => 5x = -23+38 => 5x = 15 => x=3
Then 4y = 2*3-38 => y = -8
So the solution is (3,-8)
