Question

Find the height of cylinder

whose volume is 1.54cm and diameter of its base is 140cm

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.
