Answer 2

$\large\bold\green{\underline{Question:-}}$

➻ Find the height of a cylinder when its volume and radius are given As : V=1650 cm 3 , r=5 cm

➻ Given,

✯ Volume = 1650 cm³

✯ r = 5 cm

$\boxed{\large{\bold{Volume\:of\: cylinder=\pi r{}^{2}h}}}$

$\large\bold\orange{\underline{Solution:-}}$

$\large\implies$ Volume = πr²h

$\large\implies$ π = 22/7

$\large\implies$ 1650 = 22/7 × (5)² h

$\large\implies$ 1650 = 22/7 × 25h

$\large\implies$ 1650 × 7 = 22 × 25h

$\large\implies$ 11550 = 550h

$\large\implies$ 11550/550 = h

$\large\implies$ 21 = h

$\large\implies$ $\boxed{\large{\bold{\purple{Height=21\:cm}}}}$

Therefore, height of cylinder is 21 cm...
