Question
Find the radius $ r $ of a cylinder if diameter $d = 4\, \text{mm}$ and height $h = 4\, \text{mm}$.
Answer
$2\, \text{mm}$
Explanation
To find radius $ r $ use formula:
$$ d = 2 \cdot r $$After substituting $d = 4\, \text{mm}$ we have:
$$ 4\, \text{mm} = 2 \cdot r $$ $$ r = \dfrac{ 4\, \text{mm} }{ 2 } $$ $$ r = 2\, \text{mm} $$This page was created using
