Question

find the height of the cylinder whose volume is 1.54 metre cube and diameter of the base is 140 CM​

Answer 1

Answer:

volume of cylinder =1.54m=154cm

diameter=140cm

radius =70cm

$volume = 154 \\ \pi {r}^{2} h = 154 \\ \frac{22}{7} \times {70}^{2} h = 154 \\ h = \frac{154 \times 7}{22 \times 70 \times 70} \\ h = \frac{1}{550}$

Answer 2

Answer:volume of cylinder=πr^2h

1.54=22/7*1.4/2*1.4/2*h

1.54=22/7*7/10*7/10*h

1.54=11*1/5*7/10*h

1.54=77/50h

77=77h

H=1 m

Hope this helps you
