Question

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

Answer 1

volume of cylinder =pie*r*r*h

154cm=22/7*70*70*h

154=22/7*4900*h

154=22*700*h

h=15400/154

h=100cm

Answer 2

Answer:

Given, Diameter, d =140cm

Therefore, Radius, r=140/2=70cm

and height =1.54m³

Now, Volume of the cylinder =1/3πr²h

1.54 =1/3×22/7×70×70×h

1.54=15400/3×h

h=15400×3/15400

. h=3m

Therefore The height of the cylinder is 3m
