Question

how much water will be contained in a cylindrical cement tank if the diameter of a tank is 7m and hieght is 6 times the radius

Answer 1

Answer:

Step-by-step explanation:

Water contained in the tank= volume of tank

Radius= 7/2m

Height =6×7/2

=21m

Volume of cylinderical tank= πr²h

On substituting the values

Answer will come

Volume of tank is808.5cm³

Answer 2

Diameter of the tank=7m

Radius of the tank = Diameter/2

=7/2=3.5 m

Height of the tank = 6× radius

=6 ×3.5

=21m

we know that,

Volume of cylinder=πr^2 h cu.units

=

$\frac{22}{7} \times 3.5 \times 3.5 \times 21$

=808.5 m^3

$1 {m}^{3} = 1000 \: litres$

So,

$808.5 {m}^{3} = 808.5 \times 1000 \\ = 808500 \: litres$

1000 litres = 1 kl

So, 808500 litres=808500/1000

=808.5kl

808.5 kl of water will be contained in the cylindrical tank.
