Question
Find the volume $ V $ of a sphere if radius $r = 9.6\, \text{cm}$ and diameter $d = 19.2\, \text{cm}$.
Answer
$1179.648\pi\, \text{cm}^3$
Explanation
To find volume $ V $ use formula:
$$ V = \dfrac{ 4 \cdot r^3 \cdot \pi}{ 3 } $$After substituting $r = 9.6\, \text{cm}$ we have:
$$ V = \dfrac{ 4 \cdot \left( 9.6\, \text{cm} \right)^{3} \cdot \pi}{ 3 } $$ $$ V = \dfrac{ 4 \cdot 884.736\, \text{cm}^3 \cdot \pi}{ 3 }$$ $$ V = \dfrac{ 3538.944\, \text{cm}^3 \cdot \pi}{ 3 }$$ $$ V = 1179.648\, \text{cm}^3 \cdot \pi $$This page was created using
