For this case we have by definition, that the surface area of a cylinder is given by:
[tex]SA = 2 \pi * r * h + 2 \pi * r ^ 2[/tex]
Where:
A: It's the radio
h: It's the height
According to the given data we have:
[tex]SA = 2 \pi * (5) * 20 + 2 \pi * (5) ^ 2\\SA = 200 \pi + 50 \pi\\SA = 250 \pi\\SA = 785 \ units ^ 2[/tex]
ANswer:
[tex]785 \ units ^ 2[/tex]
