Question

What is the approximate radius of a sphere of volume 528 m³? round the answer to hundreth

Answer 1

$\\ \sf\longmapsto V=\dfrac{4}{3}πr^3$

$\\ \sf\longmapsto 528=\dfrac{4}{3}πr^3$

$\\ \sf\longmapsto \pi r^3=528\times \dfrac{3}{4}$

$\\ \sf\longmapsto πr^3=32(3)$

$\\ \sf\longmapsto \pi r^3=96$

$\\ \sf\longmapsto 3.14r^3=96$

$\\ \sf\longmapsto r^3=\dfrac{96}{3.14}$

$\\ \sf\longmapsto r^3=30.57$

$\\ \sf\longmapsto r=3.09m=3.1m$

Answer 2

$\large \boldsymbol {} \sf V_{sp}=\dfrac{4}{3} \pi r^3 \\\\ \displaystyle \\ \frac{4}{3} \pi r^3=528 \ m^3 \\\\\\ r=\sqrt[3]{\sf \frac{528}{\pi } \cdot \frac{3}{4} } \approx5,0\underline 13\approx5,01$
