Answers: The rational numbers in that list are:
- 1
- -79
- 0.3125
Recall that an irrational number cannot be written as a simple fraction, so the numbers that can be written in a simple fraction are the ones that are rational. Thus, the numbers in the previous list are rational because you can convert them into simple fractions.
Answer: Avery overestimated the amount by about 13.8%.
The actual area of the pipe is about 11.04 in^2. This is found by using the formula. A = pi(r^2). The actual radius is 2 - 0.125 = 1.875
The measurement Avery found was 12.56 in^2, because he used 2 for the radius.
To find the percent increase, we use the formula below.
(12.56 - 11.04) / 11.04 = 13.8%
