 Hi and how are you all today? The question says a patient in a hospital is given soup daily in a cylindrical bowl of diameter 7 cm. If the bowl is filled with soup to a height of 4 cm, how much soup the hospital has to prepare daily to serve 250 patients. So let this be a cylindrical bowl in which the soup is being served. It is being filled with soup till the height of 4 cm. Now the diameter is given to us as 7 cm. So the radius will be half of it that is 3.5 cm. Now we need to find out how much soup the hospital has to prepare daily to serve 250 patients. That means firstly we will be finding out for one patient the volume of the soup and then for 250 patients. The diameter is given to us as 7 cm. Therefore the radius is equal to 3.5 cm. That is half of it. The height will be taken to be as 4 cm. So soup served in one serving is equal to what? It is equal to the volume of the bowl right. That is further equal to pi r square h 22 by 7 r is 3.5 the whole square r square and h is 4. So this whole will be in cm cube and the answer comes out to be 1 point that is 154 cm cube. Now served 250 patients will be equal to 154 cm cube into 250 that is equal to 385 double 0 cm cube. To convert it into liters we have the answer as 38.5 liter as we know the relationship is that 1000 liter is equal to 1 cm cube. This ends my session. Hope you understood it well. Have a nice day.
