Find the volume $ V $ of a cylinder if diameter $d = 10$ and height $h = 11$.
Answer
$V = 275\pi$
Explanation
STEP 1: find radius $ r $
To find radius $ r $ use formula:
$$ d = 2 \cdot r $$After substituting $ d = 10 $ we have:
$$ 10 = 2 \cdot r $$ $$ r = \dfrac{ 10 }{ 2 } $$ $$ r = 5 $$STEP 2: find volume $ V $
To find volume $ V $ use formula:
$$ V = r ^{ 2 } \cdot h \cdot \pi$$After substituting $ r = 5 $ and $ h = 11 $ we have:
$$ V = 5 ^{ 2 } \cdot 11 \cdot \pi$$$$ V = 25 \cdot 11 \cdot \pi $$$$ V = 275\pi $$This page was created using
