Question

Find the height of cylinder rules volume is 1.54 m cube and diameter of the base is 140 cm

Answer 1

radius of cylinder=70cm
volume of cylinder=15400cm³
22/7*r²*h=15400
h=15400*7. * 1. * 1.
22 *70. 70
h==11cm

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

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

$\rightarrow{ h = 1}$

Hence, height of the cylinder is 1 m.
