Answer:

A ≈ 494.80 [tex]mm^{2}[/tex]

V = 827.02 [tex]mm^{3}[/tex]

Step-by-step explanation:

height ( h ) = 13 mm

radius ( r )  = [tex]\frac{9mm}{2}[/tex] = 4.5 mm

Surface area  = [tex]2\pi rh + 2\pi r[/tex]

                      = 2π(4.5)(13) + 2π(4.5)

                      ≈ 494.80 [tex]mm^{2}[/tex]

Volume = [tex]\pi r^{2} h[/tex]

             = [tex]\pi (4.5)^{2} (13)[/tex]

             = 827.02 [tex]mm^{3}[/tex]
