Find the radius $ r $ of a cone if diameter $d = 9$ and height $h = 5$.
Answer
$r = \frac{ 9 }{ 2 }$
Explanation
To find radius $ r $ use formula:
$$ d = 2 \cdot r $$After substituting $ d = 9 $ we have:
$$ 9 = 2 \cdot r $$ $$ r = \dfrac{ 9 }{ 2 } $$ $$ r = \frac{ 9 }{ 2 } $$This page was created using
