Find the volume $ V $ of a cylinder if diameter $d = 8.2$ and height $h = 4.9$.
Answer
$V = 82.369\pi$
Explanation
STEP 1: find radius $ r $
To find radius $ r $ use formula:
$$ d = 2 \cdot r $$After substituting $ d = 8.2 $ we have:
$$ 8.2 = 2 \cdot r $$ $$ r = \dfrac{ 8.2 }{ 2 } $$ $$ r = 4.1 $$STEP 2: find volume $ V $
To find volume $ V $ use formula:
$$ V = r ^{ 2 } \cdot h \cdot \pi$$After substituting $ r = 4.1 $ and $ h = 4.9 $ we have:
$$ V = 4.1 ^{ 2 } \cdot 4.9 \cdot \pi$$$$ V = 16.81 \cdot 4.9 \cdot \pi $$$$ V = 82.369\pi $$This page was created using
