Question
Find the volume $ V $ of a sphere if radius $r = 19\, \text{mm}$.
Answer
$\dfrac{ 27436 }{ 3 }\pi\, \text{mm}^3$
Explanation
To find volume $ V $ use formula:
$$ V = \dfrac{ 4 \cdot r^3 \cdot \pi}{ 3 } $$After substituting $r = 19\, \text{mm}$ we have:
$$ V = \dfrac{ 4 \cdot \left( 19\, \text{mm} \right)^{3} \cdot \pi}{ 3 } $$ $$ V = \dfrac{ 4 \cdot 6859\, \text{mm}^3 \cdot \pi}{ 3 }$$ $$ V = \dfrac{ 27436\, \text{mm}^3 \cdot \pi}{ 3 }$$ $$ V = \frac{ 27436 }{ 3 }\, \text{mm}^3 \cdot \pi $$This page was created using
