After pour the water in first cuboid then measure the volume of water.<br />2. After pour the same water in first cylinder , the volume of water was not changed , we know the volume and cylinder height of water level.<br />3. After we find the area of cylinder = V/h , then note the area and diameter of the first cylinder.<br />4. After repeat the process with 2 and 3 cylinders, we know the perfect areas of 3 different cylinders and relate with the diameter or circumference of the cylinder.<br />5. We can find the new relation with Area and diameter<br />Area and circumference<br />Any one of this must be either repeated or not we don't know.<br />I don't have proper equipment to do this.Mahesh Babu Komerahttps://youtube.com/@massmaheshpalnadunoreply@blogger.comtag:blogger.com,1999:blog-8256492698354362046.post-20923869435727441032021-06-07T09:47:56.906+10:002021-06-07T09:47:56.906+10:00Thpughtfull excercise to know the effectiveness of...Thpughtfull excercise to know the effectiveness of the Teaching Learni g Process, the understanding of the students<br /><br />Thanks for sharing.
