Question

Find the height of the cylinder was volume is 1.54m3 and diametre of the base is 140 cm.

Answer 1

Given
volume=1.54m3
diameter=140cm
Therefore, radius=140divided by2
=70cm
since it is in meter
Therefore, 70by100=0.7m
Therefore, volume of cylinder=1.54mcube
pi.rsquare.h=1.54mcube
22/7.0 7.07.h=1.54
22.0.1.0.7.h=1.54
1.54 .h=1 54
h=1.54/1.54
h=1m
Therefore, height of the cylinder is 1m

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.
