Answer: 301mm^3
Step-by-step explanation:
V=πr^2h/3
volume= 3.14 * 6^2 * 8/3
301mm^3

Answer:
x int... (8,0)
y int... (0,4)
Step-by-step explanation:
Answer:
x=6, y = -9
Step-by-step explanation:
6x + 2y = 18
-4x - 2y = -6
Add the two equations together to eliminate y
6x + 2y = 18
-4x - 2y = -6
------------------------
2x +0y = 12
Divide by 2
2x/2 = 12/2
x = 6
Then find y
6x+2y = 18
6*6 +2y = 18
36+2y = 18
Subtract 36 from each side
36+2y-36 = 18-6
2y = -18
Divide by 2
2y/2 = -18/2
y = -9
