Since the lateral area of a cylinder is a circumference, which area is defined by the following formula:
[tex]A=\pi r^2[/tex]since the cylinder has 2 of them the the total lateral area is
[tex]2\pi r^2[/tex]where r is the radius, that is 6 ft. then we replace 6 in the previous formula obtaining
[tex]2\pi(6^2)=72\pi\approx226.1946ft^2[/tex]
