3/6 = x/7
Multiply x and 6, 3 and 7:
6x = 7*3
x = 21/6
x = 7/2
Since the circumference is 80, you know that the equation used was:

Divide by pi and you'd get d = 25.465
Divide that by 2 to get your radius.
25.465 / 2 = 12.723 = r
The area formula for a circle is

So,

= 508.544 square feet
The likelihood is impossible.
This is because in the chart, the only colors depicted are red, blue, and green and not black. Because of this, black is impossible to be drawn.
Hope this helps!
