Question

The diameter of a cylindrical tank is 24.5 m depth 8 m . how many metric tons of water will it hold ?

Given

Diameter = 24.5 m

height = 8 m

1 metric ton = 1000 kg

To find

volume of Tank in metric tons .

As we know :

volume of circular cylinder

$\pi {r}^{2} h$

$volume = \frac{22}{7} \times \frac{245}{20} \times \frac{245}{20} \times 8 \\ volume = \frac{22}{7} \times \frac{49}{4} \times \frac{49}{4} \times 8 \\ v = \frac{22}{7} \times \frac{49}{4} \frac{49}{2} \times4 \\ v = \frac{11}{1} \times \frac{7}{4} \frac{49}{1} \times 4 \\ v = 11 \times 7 \times 49 \\ v = 3773$

1 m cube = 1000 kg

3773 m cube = 3773×1000

3773 m cube = 3773000 kg

1 metric tone = 1000kg

3773000kg = 3773000÷1000

= 3773 metric ton .

hence we got answer as 3773 metric tone .
