Find the height of the cylinder whose volume is 1.54 $m^3$ and diameter of the base is 140 cm ?

Volume of cylinder = 1.54 $m^3$   

Diameter of cylinder = 140 cm = 1.40 m

Radius( r )$= \frac{d}{2} = \frac{140}{2} = 70 cm$

Volume of cylinder$= \pi r^{2}h$

$1.54 = \left(\frac{22}{7}\right)\times 0.7\times 0.7\times h$

$h =\frac{1.54\times 7}{(22\times 0.7\times 0.7) }$

$h = 1$

Hence, height of the cylinder is 1 m.
