45 units and is centered at

A circle has a radius of

(-2.4, - 4.8).

What is the equation of this circle?

The correct question is:

A circle has a radius of 45 units and is centered at (-2.4, - 4.8).

What is the equation of this circle?

Answer:

Equation of the circle is;

(x + 2.4) ² + (y + 4.8) ² = 2304

Step-by-step explanation:

The standard equation of a circle is;

(x - a) ² + (y - b) ² = r²

where;

(a, b) is the center of the circle and r is the radius of the circle

Now, from the question, the circle is centered at (-2.4, - 4.8) and the radius is 45

Thus, plugging those values into the standard form of equation of a circle, we have;

(x - (-2.4)) ² + (y - (-4.8)) ² = 48²

This gives;

(x + 2.4) ² + (y + 4.8) ² = 2304
