Question

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

Answer 1

Answer:

$140cm = 1.4m \\ volume = \pi {r}^{2} h \\ 1.54 = 3.14 \times ( \frac{1.4}{2} )^{2} \times h \\ 1.54 = 3.14 \times 0.49\times h \\ h = 1.0009099181$

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.
