Question

find the height of the cylinder whose volume is 1. 54 m3 and diameter of the base is 140 cm.

Answer 1

HEY!!!
HERE IS UR ANSWER

We know that
volume of cylinder is pie ×r^2×h
1.54=22/7×70×70×h
1.54×7÷22×70×70=h
1.54÷22×10×70=h
154÷22×100×700=h
7÷70000=h
1÷10000=h
0.0001=h

Hence height of cylinder is 0.0001m

Answer 2

Volume of cylinder = 1.54 m ³

and diameter of cylinder = 140 cm

Radius (r) = $\frac{d}{2}=\frac{140}{2}$=70 cm

Volume of cylinder = πr²h

$⇒ 1.54 = \frac{22}{7} \times 0.7 \times 0.7 \times h$

After simplifying, we get the value of h that is

$h = \frac{1.54 \times 7}{22 \times 0.7 \times 0.7}$

$\longrightarrow{h = 1}$

Hence, height of the cylinder is 1 m.
