Find the volume $ V $ of a sphere if radius $r = 9.6$ and diameter $d = 19.2$.
Answer
$V = 122.88\pi$
Explanation
To find volume $ V $ use formula:
$$ V = \dfrac{ 4 \cdot r^2 \cdot \pi}{ 3 } $$After substituting $ r = 9.6 $ we have:
$$ V = \dfrac{ 4 \cdot 9.6^2 \cdot \pi}{ 3 } $$ $$ V = \dfrac{ 4 \cdot 92.16 \cdot \pi}{ 3 }$$ $$ V = \dfrac{ 368.64 \cdot \pi}{ 3 }$$ $$ V = 122.88 \cdot \pi $$This page was created using
