Question
Find the volume $ V $ of a cylinder if diameter $d = 6.1\, \text{cm}$ and height $h = 4.7\, \text{cm}$.
Answer
$67.3745\pi\, \text{cm}^3$
Explanation
STEP 1: find radius $ r $
To find radius $ r $ use formula:
$$ d = 2 \cdot r $$After substituting $d = 6.1\, \text{cm}$ we have:
$$ 6.1\, \text{cm} = 2 \cdot r $$ $$ r = \dfrac{ 6.1\, \text{cm} }{ 2 } $$ $$ r = 3.05\, \text{cm} $$STEP 2: find volume $ V $
To find volume $ V $ use formula:
$$ V = h ^{ 2 } \cdot r \cdot \pi$$After substituting $r = 3.05\, \text{cm}$ and $h = 4.7\, \text{cm}$ we have:
$$ V = 4.7\, \text{cm} ^{ 2 } \cdot 3.05\, \text{cm} \cdot \pi$$$$ V = 22.09\, \text{cm}^2 \cdot 3.05\, \text{cm} \cdot \pi $$$$ V = 67.3745\pi\, \text{cm}^3 $$This page was created using
