Question

Find the height of cylinder whose volume is 1.54m cube and diameter base is 140 cm

Answer 1

volume of cylinder is pir2h
volume of cylinder is 1.54m cube.
1.54=22/7 ×0.7×0.7×h
1.54=15.4×h/10
15.4/15.4=h
h=1m
hence the height of the cylinder is 1 metre

Answer 2

Volume of cylinder = 1.54 m ³

and diameter of cylinder = 140 cm

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

Volume of cylinder = πr²h

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

After simplifying, we get the value of h that is

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

$⇒ h = 1$

Hence, height of the cylinder is 1 m.
