Find the height of the cylinder whose volume is 1.54 m3 and diameter of the base is140 cm?
Solution and Explanation
Diameter of the base = 140 cm
Radius (r) of the base = \(\frac{140}{2} = 70\ cm =\frac{70}{100}\ m\)
Volume of cylinder = \(\pi r^2h\)
\(1.54 = (\frac{22}{7})×0.7×0.7×h\)
\(h = \frac{(1.54×7)}{(22×0.7×0.7)}\)
h = 1 m
Hence, the height of the cylinder is 1 m.
