Answer :
Step 1
Write out the formula for volume of cylinder
[tex]\begin{gathered} \text{Volume of cylinder = }\pi r^2h \\ \end{gathered}[/tex]r = radius
h = height
pi = 3.142
Step 2
write out the parameters
diameter = 4 feet
radius = diameter/2 = 4/2 = 2 feet
height = 2 feet
Step 3
input values in the foemula
[tex]\begin{gathered} \text{Volume of a cylinder = }\pi r^2h \\ =\text{ 3.142 }\times2^2\text{ }\times\text{ 2} \\ =\text{ 3.142 x 4 x 2} \\ =\text{ 25.136} \end{gathered}[/tex]
