Answer:
[tex]SA=62.8\ ft^2[/tex]
Step-by-step explanation:
we know that
The surface area of a cylinder is equal to
[tex]SA=2\pi r^{2}+2\pi rh[/tex]
we have
[tex]h=3\ ft[/tex]
[tex]r=4/2=2\ ft[/tex] ----> the radius is half the diameter
assume
[tex]\pi =3.14[/tex]
substitute
[tex]SA=2(3.14)(2)^{2}+2(3.14)(2)(3)[/tex]
[tex]SA=62.8\ ft^2[/tex]
