Question

qual e o volume de um cone equilaterocujo raio da base e 6 m?

Answer 1

$V = \dfrac{1}{3}\,.\,\pi\,.\, r^{3}\,.\,\sqrt{3}\rightarrow V = \dfrac{1}{3}\,.\,\pi\,.\, 6^{3}\,.\,\sqrt{3}\rightarrow V = \dfrac{1}{3}\,.\,\pi\,.\, 216\,.\,\sqrt{3}\rightarrow \\\\ \boxed{V=72\pi\sqrt{3}\,\,\text{m}^{3}}$
