Question

Find the height of the cylinder whose capacity is 1540 L and diameter of the base is 140 cm?

• A. 1 m
• B. 10m
• C. 10cm
• D. 1cm

Answer 1

The correct option is A

1 m

It is given that diameter of the base is 140 cm. Therefore, the radius is 70 cm.
$\because$ 1 $m^3$ = 1000 L
So, 1540 L is equivalent to $1.54m^3$
Volume of Cylinder = $\pi r^{2}h$
$\Rightarrow$ 1.54 $m^3$ = $\frac{22}{7}$ $\times$ 0.7 $\times$ 0.7 $\times$ h
$\Rightarrow$ h = 1 m
