Step-by-step explanation: The formula for radius to area is: A = πr2.
Ответ:
D
Step-by-step explanation: We first need to solve the inequality.
First subtract 10 from both sides to get -x < -8.
Now divide both sides by -1, but watch out.
If you multiply or divide both sides of an inequality by
a negative number, you must switch the direction of the inequality sign.
So we have x > 8.
Start with an open dot at 8 and draw and arrow to the right.
We use an option dot since x is greater than but not equal to 8.
So option D is your answer.
