For 1 cylinder: 226.08 cubic inches
For all cylinders (overall): 678.24 cubic inches
Since I'm tired....
Formula: Pi × (radius × radius) × height
 
        
             
        
        
        
to get the equation of any straight line, we simply need two points off of it, so hmmm let's use say (-1 , -1.25) and (8 , -3.5)

Answer:
y = 4x + 32
Step-by-step explanation:
Given: Temperature at sunrise = 32°F
y is the temperature after x hours of sunrise
Temperature change is 4°F/hour.
The equation of a line in slope intercept form is given by 
y = mx +c 
where m is the slope, which is the change in value of y to the value of x 
and c is the value of y at x = 0
At sunrise, x =0 and y =32
∴ c = 32
Also we see that the change in temperature to that of time is 4/1 = 4
∴ m = 4
Substituting the values of m and c in the equation of line, we have
y = 4x +32
