Answer:
25.12 millimeters is your answer.
Step-by-step explanation:
Circumference can be solved by using the equation:
c = 2πr or c = πd
Note that diameter (d) is equal to 8. Plug in 8 for d.
c = (8)(π)
Also note that π = 3.14. Multiply
c = (8)(3.14)
c = 25.12 millimeters.
25.12 millimeters is your answer.

Answer:
1. x = ±9
2.
3. 12 and -12.
4. Antoine is incorrect. There exists two solutions x=5 and x= -5.
Step-by-step explanation:
According to the questions,
Problem 1.
i.e.
i.e. x = ±9.
Problem 2.
i.e.
i.e.
i.e.
Problem 3. [tex]f(x)=x^{2}-144[tex]
To find the roots, we take, [tex]x^{2}-144=0[tex] i.e. [tex]x^{2}=144[tex] i.e. x = ±12.
Thus, the options are 12 and -12.
Problem 4. We have [tex]f(x)=x^{2}+25[tex]
For the roots, we take, [tex]x^{2}+25=0[tex] i.e. [tex]x^{2}=25[tex] i.e. x = ±5.
Thus, Antoine is not correct and two solutions namely x=5 and x= -5 exists.
