Question

find the height of the cylinder whose volume is 1.54 metres cube and diameter of the base is 140 CM

Answer 1

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

Volume of the cylinder=1.54m^3
Diameter=140cm
Radius=140/2=70cm=0.7m
Height=?

1.54=22/7*0.7*0.7*h
1.54=11*7/5*7/10*h
1.54*5*10/11*7*100
=1m(by cutting)

Answer= Height=1m
