Answer:
15.71 metros cúbicos de aceite transportará el depósito del camión.
Step-by-step explanation:
Un camión transporta aceite de oliva en un deposito con forma de cilindro de 1 m de radio y 5 m de altura.
Para calcular la cantidad de aceite que transportará se debe calcular el volumen del depósito, siendo con forma de cilindro. El volumen de dicha figura es calculada como V=π*r²*h, donde r es el radio y h es la altura.
En este caso, el volumen del depósito cilíndrico es:
V=π*( 1 m)²*5 m
Resolviendo:
V=15,71 m³
<u><em>15.71 metros cúbicos de aceite transportará el depósito del camión.</em></u>
