Question

Find the height of a cylinder whose volume is 1.54m3 and diameter of base is 140 cm

Answer 1

Answer:

Given:-

Volume of the cylinder = 1.54m³

Diametre of the base = 140cm

Radius of the base = 140/2  

= 70cm  

= 0.7m

Volume of cylinder = πr²h

1.54 = 22/7*0.7²*h

1.54*7/22*0.7*0.7 = h

h = 1

Height = 1m Ans.

Ans.) The height of the cylinder is 1m.

Answer 2

Answer:

Given, volume of the cylinder

=1.54m³

=154/100×(100)³ cm³

and diameter of the base=140 cm

radius of the base=140/2

=70cm

Let height of the cylinder be x cm

We know that, volume of the cylinder=

= πr²x

154×(100)²

=22/7×(70)²x

=⟩154×(100)²=22/7×70×70×x

=⟩154×(100)²=22×700× x

=⟩x=154×(100)²/22×700 = 154 × 100 × 100 /22×700=100cm

Hence,the height of the cylinder is 100 cm.
