Question

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

• A. 1 m
• B. 10 m
• C. 10 cm
• D. 1 cm

Answer 1

The correct option is A

1 m

It is given that diameter of the base is 140 cm. Therefore, the radius is 70cm.
$\because$ 1$m^3$ = 1000L
So, 1540L is equivalent to 1.54m³
Volume of Cylinder = π$r^2$h
$\Rightarrow$ 1.54$m^3$ = $\frac{22}{7}$ $\times$ 0.7 $\times$ 0.7 $\times$ h
$\Rightarrow$ h = 1 m.
