Answer:
A = 744 meters B = 489 meters
Step-by-step explanation:
A = B + 255
2B - A = 234
-2B -2B Subract the -2B from both sides
-A = -2B + 234
A = 2B - 234 Divide by -1 to get A alone
B + 255 = 2B - 234 Set both equations equal to each other
- B -B
255 = B - 234
+234 +234
489 = B
Plug 234 in for B in the original equations
A = 489 + 255
A = 744
Answer: D
Step-by-step explanation:

Answer:
V=11858.98
Step-by-step explanation:
V=r^2*pi*h
first find r
r=d/2
d=1.4(19.75)
d=27.65
r=27.65/2
r=13.825 ft
plug into volume equation
V=13.825^2*pi*19.75
V=11858.97771
V=11858.98 ft^3
