Answer:

$490.9\ ft^{2}$

Step-by-step explanation:

we know that

The total area is equal to

$A=10(h)+2\pi r(h)+10(h)$

we have

$h=9\ ft$

$r=5.5\ ft$

$\pi=3.14$

substitute

$A=10(9)+2(3.14)(5.5)(9)+10(9)$

$A=490.9\ ft^{2}$

2. Dilute hydrochloric acid reacts with zinc to form zinc chloride and hydrogen.

DIA [1.3K]

Step-by-step explanation:

Zn + 2HCl => ZnCl2 + H2

Moles of Zn = 13g / (65.38g/mol) = 0.198mol

Volume of HCl = 0.396mol / (0.25mol/dm³) = 1.58dm³.

Volume of H2 = 0.198mol * (22.4dm³/mol) = 4.43dm³.
