Area of circle = πr²

Area:
= 3.14 x (7.1)²

= 3.14 x 50.41

= 158.2874

= 158.29 (nearest hundredth)

Answer: 158.2874

Explanation:
The area of a circle is pi times the radius squared (A = π r²).

Our radius is 7.1 so we square it which is basically the equivalent of doing 7.1 x 7.1 which equals 50.41 then we multiply this by pi which is 3.14 so it 50.41 x 3.14 = 158.2874

I know she graphed it correctly but i don't know the steps she took to graph it

She graphed it correctly.

The inequality $3y \le 2x$ is the same as $y \le \frac{2}{3}x$ after dividing both sides by 3 to isolate y.

From here you graph $y = \frac{2}{3}x$ which is a straight line through (0,0) and (3,2). This line is made solid because of the "or equal to" as part of the inequality sign above.
