If anyone knows the answer plz tell me, thank you

Step-by-step explanation:

The equation of a circle with center and radius is given by:

.

We're given:

Since we're given the circle's center, we just need to find the radius. Because the center of the circle is at (0, 0), the radius will be equal to the distance from (-3, 4) and (0, 0).

For points and , the distance between them is given by the formula:

Let:

The distance between these two points must be:

Therefore, the radius of the circle is 5 and the equation of the circle is:

answer: .75 km
