Answer:

2A/r^2 = pi

Step-by-step explanation:

A=1/2πr^2

multiply each side by2

2A = 2*1/2 pi r^2

2A = pi*r^2

divide each side by r^2

2A/r^2 = pi r^2/r^2

2A/r^2 = pi

Step-by-step explanation:

$slope = \frac{rise}{run} = \frac{y2 - y1}{x2 - x1} \\ = \frac{ - 7 - 13}{5 - ( - 3)} \\ = \frac{ - 20}{8} \\ = \frac{ - 2 \times 10}{2 \times 4} \\ = \frac{ - 10}{4} \\ = \frac{ - 2 \times 5}{ 2 \times 2} = \frac{5}{2}$
