Find the volume $ V $ of a sphere if radius $r = 12$.
Answer
$V = 192\pi$
Explanation
To find volume $ V $ use formula:
$$ V = \dfrac{ 4 \cdot r^2 \cdot \pi}{ 3 } $$After substituting $ r = 12 $ we have:
$$ V = \dfrac{ 4 \cdot 12^2 \cdot \pi}{ 3 } $$ $$ V = \dfrac{ 4 \cdot 144 \cdot \pi}{ 3 }$$ $$ V = \dfrac{ 576 \cdot \pi}{ 3 }$$ $$ V = 192 \cdot \pi $$This page was created using
