Find the volume $ V $ of a cylinder if diameter $d = 3.5$ and height $h = 3.5$.
Answer
$V = 10.7188\pi$
Explanation
STEP 1: find radius $ r $
To find radius $ r $ use formula:
$$ d = 2 \cdot r $$After substituting $ d = 3.5 $ we have:
$$ 3.5 = 2 \cdot r $$ $$ r = \dfrac{ 3.5 }{ 2 } $$ $$ r = 1.75 $$STEP 2: find volume $ V $
To find volume $ V $ use formula:
$$ V = r ^{ 2 } \cdot h \cdot \pi$$After substituting $ r = 1.75 $ and $ h = 3.5 $ we have:
$$ V = 1.75 ^{ 2 } \cdot 3.5 \cdot \pi$$$$ V = 3.0625 \cdot 3.5 \cdot \pi $$$$ V = 10.7188\pi $$This page was created using
