Question

Find the height of cylindrical vessel of diameter 1.4 m if it holds770ltrs. of water

Answer 1

Answer:

0.5 meters

Step-by-step explanation

First convert liters to meter cubed because the diameter has been given in meters and height is also required in meters (most probably). So that will be 0.77 m³.

Now the formula for volume of cylinder's volume is V=pi*R²*height

So, taking radius as 0.7 (because diameter is so half of it is 0.7), we simply put in the values and obtain the answer.

0.77=3.14(0.7²)*height

So, height=0.77/(3.14*1.5386)

Which comes out to be 0.5 meters.
