A percentage is a fraction expressed as a part of 100.

To round a decimal to the nearest hundredth, look at the third decimal place. If it is 5 or greater, round up the second decimal place by one.

The area (A) of a circle is given by the formula: $$A = \text{π}r^2$$ , where r is the radius.

A proper fraction has a numerator smaller than its denominator, while an improper fraction has a numerator that is equal to or larger than its denominator.

The volume (V) of a cylinder is given by the formula: $$V = \text{π}r^2h$$ , where r is the radius and h is the height.
