Un depósito abierto tiene forma de cono circular recto. El diámetro del circulo superior del depósito es de 8 pie y la altura es de 6 pie. Se bombea agua por el fondo del depósito, ¿cuánto trabajo se realiza para llenar el depósito hasta una altura de 2 pie?

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
