Name a tool that is used to measure the circumference of an object and Name a tool that you can use to measure the volume of an object.
One commonly used tool to measure the circumference of an object is a flexible measuring tape. To use it, wrap the tape around the object in a circular manner and note the length where the two ends meet. This will give you the circumference.
For measuring the volume of an object, a tool called a graduated cylinder is commonly used. Place the object in the graduated cylinder partially filled with water and note the change in water level. The difference in volume before and after inserting the object gives you the volume.
Note that these are just a couple of examples, and there are other tools available for these measurements depending on the specific requirements and the object being measured.
