A university designs its campus with a master plan of two concentric circles. All of the academic buildings are within the inner

Paul [167]

Answer:

$x^2+y^2=36100000$

Step-by-step explanation:

Here it is mentioned that the there are two concentric circles this means that they have the same center.

The center of the circles are the origin $(0,0)$ .

Radius of the outer circle is

$r=\dfrac{3800}{2}=1900\ \text{m}$

Equation of a circle

$(x-a)^2+(y-a)^2=r^2$

where

$a\ \text{and}\ b\ \text{are the}\ x\ \text{and}\ y\ \text{coordinates of the center}$

$r=\text{Radius of the circle}$

Here the equation will be

$(x-0)^2+(y-0)^2=1900^2\\\Rightarrow x^2+y^2=3610000$

The equation of the outer circle is $x^2+y^2=3610000$
