Question

what 2 way to find volume of balloon

Answer 1

One way is to fill the balloon with water completely and pour the same filled water into a measuring cylinder and calculate the volume from that amount of water.we can calculate radius also by assuming balloon to be spherical and using relation v=4/3πr^3.

Another way is to put a smaller container in larger container and fill the smaller container with full of water. Now fill the balloon with gas either by pumping or using another technique then place that balloon carefully inside the smaller container and submerge it completely. Some amount of water will get displaced in larger container os measure that amount of water and we calculated the volume of balloon.
