Answer:
Train A = 299 tons Train B = 50 tons
Step-by-step explanation:
Train A = x
Train B = y
x+y = 349
x= y +249
Plug in one equation into another
y+249+y= 349
Simplify
2y+249=349
Subtract 249 from both sides
2y=100
Divide both sides by 2
y=50
Plug it into the x equation to solve for x
x+50=349
-50 from both sides
x=299
The variable <em>x </em>is equal to 0.5

Step-by-step explanation:
Givens
r = 10 m
pi = 3.14
Formula
V = 4/3 * 3.14 * r^3
Solution
V = 4/3 * 3.14 * 10^3
V = 4/3 * 3.14 * 3140
V = 4186.67 m^3
