It is possible to calculate the volume of a sphere with the radius of \( 3 \) using a definite integral. Which of the following formulas is not correct?
\( \int\limits_{-3}^3\left(9-x^2\right)\,\mathrm{d}x \)
\( \pi\int\limits_{-3}^3\left(9-x^2\right)\,\mathrm{d}x \)
\( 2\pi\int\limits_{0}^3\left(9-x^2\right)\,\mathrm{d}x \)
\( \pi\int\limits_{-3}^3\left(-\sqrt{9-x^2}\right)^2\,\mathrm{d}x \)
