Height Of Cylinder = 1.5 m

Height = 150 cm

Step-by-step explanation:

GIVEN

Volume = 2.31 m

Diameter = 140 cm = 1.4 m

___________________________

TO FIND

Height Of Cylinder

___________________________

We know that,

Diameter = 2 × Radius

Radius = Diameter / 2

Radius = 140 / 2

Radius = 70

Radius = 70 cm

Radius = 0.7 m

___________________________

We know that,

Volume Of Cylinder = π × r² × h

2.31 = 22/7 × 0.7² × h

2.31 = 22/7 × 0.49 × h

Height = ( 2.31 × 7 ) / ( 22 × 0.49 )

Height = 16.17 / 10.78

Height = 1.5

Height Of Cylinder = 1.5 m

Height Of Cylinder = 150 cm

Answer:

  • 1.5m

To Find :

  • height of cylinder

Given:

  • volume of cylinder = 2.31 m³

  • Diameter = 140cm

• Radius (r) = 140/2 = 70cm=70/100=7/10cm

▪︎ we have to find the height of cylinder

  • let the height of cylinder be h

volume of cylinder = πr²h

↬ 2.31 = πr²h

↬ πr²h = 2.31

↦ 22/7×7/10²×h×2.31

↦ 22/7×7/10×7/10×h=231/100

↦ 22×7/100h = 231/100

↦ 154h = 231

↦ h = 231/154

↦ h=1.5m

Height of cylinder = 1.5m
