Ответ:
[tex]a) r=\sqrt[3]{\dfrac{3*4\pi }{4\pi } } =\sqrt[3]{\dfrac{12\pi }{4\pi } } =\sqrt[3]{3} =1.4(m)[/tex]
[tex]b)r=\sqrt[3]{\dfrac{3*7.2}{4\pi } } =\sqrt[3]{\dfrac{21.6}{3.1} } =\sqrt[3]{7} =1.2(m)[/tex]
Объяснение:
[tex]V=\dfrac{4}{3} \pi r^3[/tex] ⇒ [tex]r=\sqrt[3]{\dfrac{3V}{4\pi } }[/tex]
