To find height $ h $ use formula:
$$ V = \dfrac{ r ^{ 2 } \cdot h \cdot \pi}{ 3 } $$After substituting $ V = 2000 $ and $ r = 22 $ we have:
$$ 2000 = \dfrac{ 22 ^{ 2 } \cdot h \cdot \pi}{ 3 } $$$$ 2000 \cdot 3 = 22 ^{ 2 } \cdot h \cdot \pi $$$$ 6000 = 484 \cdot h \cdot \pi $$$$ h = \dfrac{ 6000 }{ 484 \, \pi} $$$$ h = 3.946 $$
