Question

Considerando π = 3, calcule o valor do raio de uma bola de basquete de volume igual a 500 cm3.

Answer 1

$\Large\boxed{\begin{array}{l}\sf V=\dfrac{4}{3}\pi\cdot R^3\implies R=\sqrt[\sf3]{\sf\dfrac{3V}{4\pi}}\\\\\sf R=\sqrt[\sf3]{\sf\dfrac{\diagdown\!\!\!\!3\cdot500}{4\cdot\diagdown\!\!\!\!3}}\\\\\sf R=\sqrt[\sf3]{\sf125}\\\sf R=\sqrt[\sf3]{\sf 5^3}\\\sf R=5~cm\end{array}}$
