Question

5. Brian's cylindrical water tank has a diameter of 4m and a height of 2m.

i) Find the volume of the tank (to the nearest litre)

ii)Find the depth of the water in the tank when it has 2000L of water (to the nearest
centimeter)

Answer 1

i) 25130 Liters

ii) 16 cm

Explanation:

The volume of the tank is in cubic meters, not liters. So the answer to question i) would be 25.13 cubic meters, which equals 25130 Liters.

ii) Now we find the depth. 2000 is 7.959% of 25130. 7.959% of the 2 meter height is 15.917 cm. Rounded to the nearest cm, it would be 16 cm.
