Correct Answer – Option 4 : 237006 cm3
Given:
Circumference of the tank = 396 cm
Height of the tank = 19 cm
Formula used:
Circumference of the base = 2 π r
The volume of the cylinder = π r2 h
Here, h and r is the height and radius respectively
Calculation:
Circumference of the base = 2 π r
⇒ 2 × 22/7 × r = 396
⇒ r = 63 cm
Now, Quantity of water it can hold = π r2 h
⇒ 22/7 × 63 × 63 × 19
⇒ 237006
∴ The quantity of water tank can hold is 237006 cm3
