Find the height of the cylinder whose volume if 1.54 m3 and diameter of the base is 140

Given: Volume of cylinder = 1.54 m³ and Diameter of cylinder = 140cm
∴ Radius (r) = d/2=140/2=70cm
Volume of cylinder = πr²h
⇒ 1.54=22/7×0.7×0.7xh ⇒ h= 1.54×7/22×0.7×0.7
⇒ h=154x7x10x10/22x7x7x100=1m
Hence, the height of the cylinder is 1 m.
