Find the volume $ V $ of a cylinder if diameter $d = 6.1$ and height $h = 7.2$.
Answer
$V = 66.978\pi$
Explanation
STEP 1: find radius $ r $
To find radius $ r $ use formula:
$$ d = 2 \cdot r $$After substituting $ d = 6.1 $ we have:
$$ 6.1 = 2 \cdot r $$ $$ r = \dfrac{ 6.1 }{ 2 } $$ $$ r = 3.05 $$STEP 2: find volume $ V $
To find volume $ V $ use formula:
$$ V = r ^{ 2 } \cdot h \cdot \pi$$After substituting $ r = 3.05 $ and $ h = 7.2 $ we have:
$$ V = 3.05 ^{ 2 } \cdot 7.2 \cdot \pi$$$$ V = 9.3025 \cdot 7.2 \cdot \pi $$$$ V = 66.978\pi $$This page was created using
