Question

The diameter of a cylindrical water tank is 3 meters and it’s height is 4 meters . Calculate the volume of the water tank in liters ?

Answer 1

Step-by-step explanation:

radius of tank = 3/2 = 1.5 m

height = 4m

volume of water tank = πr^2h

= π × (1.5)^2 × 4

= 6.25 ×4 π

= 25.00 π

= 25π m^3

(* 1 m^3 = 1000 liters)

volume of tank = 25π × 1000

(in liters)

= 25000π litres

Answer 2

Answer:

$diameter = 3m \\ radius = \frac{ \ 3}{2} \\ = 1.5m \\ = h = 4m \\ = volume = \pi {r}^{2} h \\ = \frac{22}{7} \times 1.5 \times 1.5 \times 4 \\ = 28.2857$
