Find the radius $ r $ of a cone if diameter $d = 27.056\, \text{cm}$ and slant height $l = 25\, \text{cm}$.
Answer
$13.528\, \text{cm}$
Explanation
To find radius $ r $ use formula:
$$ d = 2 \cdot r $$After substituting $d = 27.056\, \text{cm}$ we have:
$$ 27.056\, \text{cm} = 2 \cdot r $$ $$ r = \dfrac{ 27.056\, \text{cm} }{ 2 } $$ $$ r = 13.528\, \text{cm} $$This page was created using
