That's false
-7+9=2
and 7+9=18
The formula for the area of a circle is

We know the diameter, and the radius is half of the diameter. So the radius is 9. Now we plug that into the formula.

So the answer is B, 81 pi square feet
Answer:
The slope intercept form is y=-7x+59
Step-by-step explanation:
y-y=m(x-x1)
y-3=-7(x-8)
y-3=-7x+56
+3 +3
y=-7x+59
Answer:
y intercept (0, 4)
x intercept (4, 0)
I hope this is good enough:
Hint: Try using the Pythagorean thereom to solve it.
