Answer:
V = 38659.68 cm^3
Step-by-step explanation:
If we pretend A barrel is a cylinder we use V=πr^2h for the volume. We know h, but we need to find r
The question tells us the circumference, well how do we find circumference? C = 2πr, so we can use this to find r.
C = 2πr
56.52 = 2 * 3.14 * r Here divide both sides by 2*3.14
56.52/(2*3.14) = r
9 cm = r
Now we can just plug into the volume.
V=πr^2h
V = 3.14 * 9^2 * 152
V = 38659.68 cm^3
I feel I should mention this is all true if the circumference is in centimeters, since the question didn't specify.

Answer:
A
Step-by-step explanation:
The equation 
describes the proportional relationship between variables x and y. In this equation, k is the coefficient of proportionality.
Consider all options:
A. For the equation
the coefficient of proportionality is
B. For the equation
the coefficient of proportionality is
C. For the equation
the coefficient of proportionality is
D. For the equation
the coefficient of proportionality is
Yes, it is the hypotenuse. You can use pythagoras' theorem or the sine rule. you can use either as long as you know the two other side lengths of the triangle
No it is not proportional because y=3x and if you replace x with 2x y=3(2x) = 2(3x) = 2y
y= 2y BUT if you replace x with 2x in y= 3x + 5 youll get 2y for y meaning, its not proportional.
