Question

Given a cylindrical tank, in which situation will you find surface area and in which situation volume.

1. To find how much it can hold
2. Number of cement bags required to plaster it
3. To find the number of smaller tanks that can be filled with water from it.

Answer 1

1. We must determine the cylindrical tank's volume in order to determine how much a cylinder can contain.
2. We must determine the cylindrical tank's surface area in order to determine how many cement bags will be needed to plaster the tank.
3. We must calculate the volumes of the big cylindrical tank and one tiny tank in order to determine which smaller tanks can be filled with water from the larger tank.
