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

Answer 1

r=d/2=140cm/2=70cm

$volume \: of \: cylinder = \pi {r}^{2} h \\ 1.54 {m}^{3} = \frac{22}{7} \times ({70cm)}^{2} \times h$

$1.54 {m}^{3} = \frac{22}{7} \times 70cm \times 70c \times h$

$1.54 {m}^{3} = 22 \times 10cm \times 70cm \times h$

$1.54 {m}^{3} = 15400cm \times h$

$\frac{1540000 {cm}^{3} }{15400 {cm}^{2} } = h$

$100cm = h$

$note : \\ first \: same \: the \: unit \: when \: you \:$

$convert1.54 \: {m}^{3} \: into \: {cm}^{3} because \\ data \: is \: given \: in \: cm \: unit$
