Question

Uma esfera possui 32000 cm³ de volume. Quanto mede o raio dessa esfera

Answer 1

$\boxed{\begin{array}{l}\sf V=\dfrac{4}{3}\cdot\pi\cdot R^3\implies R=\sqrt[\sf3]{\sf\dfrac{3V} {4\pi}}\\\\\sf R=\sqrt[\sf3]{\sf\dfrac{3\cdot32000}{4\cdot3,14}}\\\\\sf R=\sqrt[\sf3]{\sf7643,31}\\\sf R=19,69~cm \end{array}}$
