If volume of sphere is $850{ \mathrm{m}}^3$ then its radius is

Concept: A sphere is indeed a solid shape with a curved surface. A sphere is indeed a solid shape with a curved surface.

Here, the volume of the sphere is $850{ \mathrm{m}}^3$.

That is,  $850 {\text{m}}^3=\frac{4}{3}\pi {\text{r}}^3$

$\Rightarrow {\mathrm{r}}^3=\frac{850\times 3\times 7}{4\times 22}=202.84$

$\Rightarrow \mathrm{r}=\sqrt[3]{202.84}=5.88 \mathrm{m}$

Hence, the radius of the sphere is $5.88 \text{m}$.
