 Hi and how are you all today? My name is Priyanka and let us discuss this question. It says the circumference of the base of a cylindrical vessel is 132 cm and its height is 25 cm. How many litres of water can it hold? So here we need to find how many litres of water it can hold. That means we need to find the volume of this cylindrical vessel, isn't it? So before proceeding on with the solution we should be well versed with the volume with the formula that is volume of a cylinder that is equal to pi r square h where r is equal to the radius of the cylindrical base and h is the height of the cylinder. Right, so this becomes the key idea of our question further. Now according to this question there is a cylindrical vessel whose circumference of the base is given to us. Also we are given the height of this cylinder as 25 cm. Right, first of all with the help of this circumference we will be finding the radius of this cylinder and substituting the radius and the height in the formula that we know we can find out how much water it can hold. Here we are given the circumference of the base 132 cm. Now with the help of our previous knowledge we can write that the circumference formula is equal to 2 pi r remember that means 2 pi r is equal to 132 cm that implies r is equal to 132 the whole divided by 2 into the value of pi is known to us as 22 by 7 so 7 will go in the numerator that implies the value of r is let us simplify it further 21 cm that is 3 into 7 so we know the value of r we know the value of h which is given to us as 25 cm let us find out the volume of the cylinder the cylindrical vessel so that is equal to pi r square h that is 22 by 7 multiplied by r square that means 2 times 21 will get multiplied multiplied by h that is 25 so we have on simplifying the value or the volume of the cylinder as this is equal to 34650 cm cube now we need to convert centimeter cube into litre because in the question we need to find out how many liters of water of water can it hold so we need to convert it into litre using this relation so that means converting centimeter cube into liters we just need to divide 34650 by 1000 and it will get converted into liters so the answer is 34.65 liters of water the cylindrical vessel can hold right so this is the required answer hope you understood the whole concept well just remember the formulas and have a good day
