Answer:

76[tex]\pi[/tex] or 238.76 [tex]units^{3}[/tex]

Step-by-step explanation:

The volume of a cylinder is V = [tex]\pi r^{2} h[/tex]

Here the radius is  r = [tex]\frac{1}{2} d[/tex] = [tex]\frac{1}{2}(4)=2[/tex]

The height is given as 19 ft

Then plug in all the numbers into the equation

V = [tex]\pi (2^{2})(19) = 76\pi = 238.76 units^{3}[/tex]
