Answer:
y= -4x+7
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.
Let's find the gradient of the line first.
Using the above formula,
Susbt. m= -4 into the equation:
y= -4x +c
Subst. a coordinate to find c.
When x=3, y= -5,
-5= -4(3) +c
-5= -12 +c
c= 12 -5
c=7
Thus the equation of the line is y= -4x +7.
We know that the volume of a Cylinder is 
We also know that Pi is 3.14, radius is 3 and Height is 4ft
So we do: 3.14*3*4
and the answer is 37.68
But rounded to the hundredths its 37.69 ft^3
