Answer:
Approximately 67.348 litres can be put in six hemispherical bowl with a diameter of 35 centimetres.
Step-by-step explanation:
The volume of a hemisphere (
), measured in cubic centimetres, is obtained from this formula:

Where
is the radius of the hemisphere, measured in centimetres.
We know that radius is the half of the diameter (
), measured in centimetres, then:

(
)


Now, we get the volume of each hemispherical bowl:


The total volume of six hemispherical bowl is:



From Physics we know that 1 litre equals 1000 cubic centimetres. Then:

Approximately 67.348 litres can be put in six hemispherical bowl with a diameter of 35 centimetres.
