well, the last part will be with a calculator, but you can simply use the area in π terms.

Answer:
false
Step-by-step explanation:
The conjecture shown in this problem statement does not follow from the examples offered. They support the notion that ...
1/x ≤ x . . . . for x ≥ 0 (<u>not x ≤ 0</u>)
There are several possible counterexamples showing the conjecture is FALSE.
- 1/0 is undefined
- 1/(-5) > -5 . . . . . . . . a case for x < 0
If the intended domain is x ≥ 0, then the conjecture can also be demonstrated to be false for 0 < x < 1:
- 1/(1/5) > 1/5
