Find the volume $ V $ of a cone if radius $r = 9$ and height $h = 15$.
Answer
$V = 405\pi$
Explanation
To find volume $ V $ use formula:
$$ V = \dfrac{ r ^{ 2 } \cdot h \cdot \pi}{ 3 } $$After substituting $ r = 9 $ and $ h = 15 $ we have:
$$ V = \dfrac{ 81 \cdot 15 \cdot \pi}{ 3 }$$$$ V = \dfrac{ 1215 \, \pi}{ 3 } $$$$ V = 405\pi $$This page was created using
