12.56 because
16(3.14)=50.24
12(3.14)=37.68
50.24 - 37.68=12.56
So the formula for volume of a cylinder is pi multiplied by radius squared times height
so the volume would be 6,725,063.56 units squared

Equation of Line
The first step is to determine the slope of the line; using the following formula


becomes




The next is to determine the equation of the line using any of the points
The formula is as thus;

Using 




Multiply both sides by x + 2




Subtract x from both sides


Hence, the equation of the line in standard form is
