Answer:

Outside the circle

Step-by-step explanation:

Let's first write the equation of this circle: (x-h)^2+(y-k)^2=r^2, where (h, k) is the center and r is the radius. Here, the center is (-6, -2). We need to find the radius, which will just be the distance from N to E:

NE = \sqrt{(-6-(-1))^2+(-2-1)^2} =\sqrt{25+9} =\sqrt{34}

The radius is √34, which means that r² = 34. So, our equation is:

(x + 6)² + (y + 2)² = 34

Plug in -10 for x and -7 for y:

(x + 6)² + (y + 2)² = 34

x² + 12x + 36 + y² + 4y + 4 = 34

x² + 12x + y² + 4y + 40 = 34

x² + 12x + y² + 4y + 6 = 0

(-10)² + 12 * (-10) + (-7)² + 4 * (-7) + 6 = 7

Since 7 > 0, we know that H lies outside the circle.

Answer:

Outside the circle

Step-by-step explanation:

Radius: NE

sqrt[(-10--6)² + (-7--2)²]

sqrt(34)

Distance NH

sqrt[(-1--6)² + (1--2)²]

sqrt(41)

Distance NH > radius,

So outside the circle

To solve this you would make a triangle, Assuming you had a piece of paper.

It would look like the picture included (where ever that is) sorry for the horrible drawing with mouse.

You can then you Pythagorean Theorem to solve this

a^{2} + b^2 =c^2

width will be (a) 

put in your variables

a^2 + 72^2 = 90^2
a^2 + 5184 = 8100

Subtract 5184 over and get 
a^2 = 2916

square root both sides and get 
a=54

the field is 54 meters wide
