What is the reason behind the inequality (∫[infinity]1 2πy dx) > (2π∫[infinity]1 y dx) when calculating the surface area of Torricelli's trumpet? A) It is a mistake in the calculation; both integrals should be equal. B) The inequality ensures the formula is consistent with Torricelli's trumpet's specific characteristics. C) The inequality simplifies the computation by reducing the integral to a known formula. D) The inequality arises due to the choice of limits of integration.
