Answer:
3,266.53
Step-by-step explanation:
Pick 2 points on ur line and use the slope formula : (y2 - y1) / (x2 - x1)
(y2 - y1) / (x2 - x1)
(-9,0)....x1 = -9 and y1 = 0
(0,6).... x2 = 0 and y2 = 6
now sub
slope = (6 - 0) / (0 - (-9) = 6/(0 + 9) = 6 / 9 = 2/3 <==
ur y intercept is where ur line crosses the y axis...and that would be (0,6)....or just 6 <==

Answer:
v=2πrh
r=d/2=8/2=4
Therefore, V=2×3.142×4×2= 50.272 ans.
-2x^2=-15-5
-2x^2=-10
x^2=-5
X≠R i am not quite sure but...hope it helps :)
