42.41 cubic meters
The volume of a cylinder is bh where b is the area of the base and h is the height of the cylinder. And since the area of a circle is pi r^2, we have this equation for the volume of a cylinder
V = pi*r^2*h
Now substitute, the known values for r and h, then calculate the result:
V = pi*r^2*h
V = 3.14159*3^2*1.5
V = 3.14159*9*1.5
V = 42.411465
V = 42.41
So the volume of the coal pile is 42.41 cubic meters.

Answer:

k = -4
Step-by-step explanation:
Given system of equations are,
-3x-3y = h
-4x + ky = 10
We have to find the values of h and k such that system of equations has no solution.
The standard form of system of equation in two variables can be given by,


And condition for the system of equations has no solution is given by,

So, by comparing the standard form of equations with given equations, the condition such that system has no solution can be written as,


=> k = -4
and 



So, the value of h and k for above given system of equations is
and k = -4.
Answer:
y = ( 5 / 9 )x + 30
Step-by-step explanation:
y - y1 = m ( x - x1 )
m = 5 / 9
y - ( 5 ) = ( 5 / 9 ) [ x - ( - 45 ) ]
y - 5 = 5 / 9 ( x + 45 )
y - 5 = ( 5 / 9 )x + 25
y = ( 5 / 9 )x + 30
