Find the volume $ V $ of a sphere if radius $r = 30$ and diameter $d = 60$.
Answer
$V = 1200\pi$
Explanation
To find volume $ V $ use formula:
$$ V = \dfrac{ 4 \cdot r^2 \cdot \pi}{ 3 } $$After substituting $ r = 30 $ we have:
$$ V = \dfrac{ 4 \cdot 30^2 \cdot \pi}{ 3 } $$ $$ V = \dfrac{ 4 \cdot 900 \cdot \pi}{ 3 }$$ $$ V = \dfrac{ 3600 \cdot \pi}{ 3 }$$ $$ V = 1200 \cdot \pi $$This page was created using
