Answer:
D. Circumference/Diameter = π
<em> hope this helps. good luck :)</em>
The point-slope form:

We have

Therefore
<h3>slope = -3 and the point (-2, 6)</h3>
------------
<h3>y + 2 = 2(x - 1)</h3>
2x - y = 4 <em>it's standard form Ax + By = C</em>
y = 2x - 4 <em>it's slope-intercept form y = mx + b</em>
y - x = 4 →<em> </em>x - y = -4 <em>t's standard form Ax + By = C</em>
The height will be 50.
To calculate area, you must know the base and height.
Since it’s already given to you, you must calculate it. Well... what times 1 gives me 50?
1x50=50
