Find the volume $ V $ of a cone if radius $r = 5$ and height $h = 4$.
Answer
$V = \frac{ 100 }{ 3 }\pi$
Explanation
To find volume $ V $ use formula:
$$ V = \dfrac{ r ^{ 2 } \cdot h \cdot \pi}{ 3 } $$After substituting $ r = 5 $ and $ h = 4 $ we have:
$$ V = \dfrac{ 25 \cdot 4 \cdot \pi}{ 3 }$$$$ V = \dfrac{ 100 \, \pi}{ 3 } $$$$ V = \frac{ 100 }{ 3 }\pi $$This page was created using
