HELP MEEEE PLZ.
i need to Find the surface area and volume

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]
