Question

The radius of thd base of a cylindrical oil can is 4m.find its height if it can contain 1408kl of oil.

Answer 1

since 1kL = 1m^3,
v = πr^2 h
16πh = 1408
h = 88/π m

Answer 2

1 kl=1ml³
Now,
We know that 1408 kilolitres =1408 m³
Volume of cube=πr²h
Radius=4 m
Height=?
22/7×4×4×h=1408
h=1408×7/22×4×4
h=28m
