Question

A cylindrical water tank contains 7,70,000 litre of water. If the radius is 3.5m find height

Answer 1

Step-by-step explanation:

volume of cylinder=πr²h

r=3.5m

v=770000

770000=3.14×3.5×3.5×h

h=20052.08

please mark my answer as brainest answer

Answer 2

Answer:

Given,

volume of cylindrical tank=770000 lit

Radius of tank=3.5m

let, 'h' be the height of the cylindrical tank.

Since,

Volume of cylinder=πr^2h

According to question,

22/7×3.5×3.5×h=770000

22/7×12.25×h=770000

22×1.75×h=770000

38.5×h=770000

h=770000/38.5

h=20000

Hence,

Height of the cylindrical tank is 20000m
