Question

Find the height of the cylinder whose volume is 1.54 m³and diameter of the base is 140cm.

Answer 1

The right answer will be 100cm.

Answer 2

Hey there !!

given that -

Radius r = 70/100 = 0.7 m

Height , h = ?

Volume of the Cylinder = 1.54 m³

⇒ πr²h = 1.54 m³

⇒
$\frac{22}{7} \times \frac{7}{10} \times \frac{7}{10} \times h \: = 1.54 \: \\ \\ = > 22 \times 7 \times h \: = 100 \times 1.54 \\ \\ = > 154 \times h = 154 \\ \\ = > h \: = \frac{154}{154} \\ \\ = > h \: = 1 \: m \:$
or 1 × 100 cm = 100cm

Hope this would help you !
