Answer

Explanation:

Step1: Identificar la fórmula del volumen del cilindro

El volumen $V$ de un cilindro se calcula con la fórmula $V=\pi r^{2}h$, donde $r$ es el radio y $h$ es la altura.

Step2: Sustituir valores dados

Dado que $r = 3$ pies y $h=12$ pies, y $\pi\approx3.14$, entonces $V = 3.14\times3^{2}\times12$. Primero, calculamos $3^{2}=9$. Entonces $V=3.14\times9\times12$. $3.14\times9 = 28.26$, y $28.26\times12=339.12$.

Answer:

$339.12$
