Question:
Solution:
Remember that the total area surface of the cylinders is given by the formula:
[tex]S\text{ = 2}\pi rh+2\pi r^2[/tex]
where r is the radius of the cylinder and h is its height. Now, in this case, we have that r= 10 m and h = 5m, then replacing these values in the previous equation we obtain:
[tex]S\text{ = 2}\pi(10)(5)+2\pi(10^2)=942.48^{}[/tex]
then, we can conclude that the correct answer is:
[tex]S\text{ =}942.48^{}[/tex]
