Answer- 1,200
Explanation- the formula of volume is length x width x height. So you just multiply those three numbers. Hope this helped!
To find corresponding angles and sides, you look at the name of the figure and see which one correlates.

Answer:
r = 3.42
Step-by-step explanation:
the equation for volume is V = pi r^2 h
550 = 3.14 r^2 15
36 2/3 = 3.14 r ^2
11.6772824 = r^2
3.41720389 = r
r = 3.42
We know that if two lines are Perpendicular then Product of Slopes of both of these Perpendicular lines should be Equal to -1
Given : Equation of 1st Perpendicular line is -x + 3y = 9
This can be written as :
3y = x + 9
y = x/3 + 3
Comparing with standard form : y = mx + c
we can notice that slope of 1st Perpendicular line = 1/3
Slope of 1st Line × Slope of 2nd line = -1
1/3 × Slope of 2nd line = -1
Slope of 2nd line = -3
We know that the form of line passing through point (x₀ , y₀) and having slope m is :
y - y₀ = m(x - x₀)
Here the 2nd Perpendicular line passes through the point (-3 , 2)
x₀ = -3 and y₀ = 2 and we found m = -3
⇒ y - 2 = -3(x + 3)
⇒ -3x - 9 = y - 2
⇒ -3x - y = 7
