An airport is located at the point (-4, 3). The noise of planes landing and taking off can be heard up to 3 miles away. Write the inequality of a circle that represents the situation

The correct answer is:

Step-by-step explanation:

The airport is located at the point (-4 , 3). Thus we can consider the center of the circle to be this particular point.

Since the noise can be heard till 3 miles away, this implies we can consider the radius of the circle to be 3.

We all know the general equation of circle with center at ( , ) with radius r is given by:

Here the value of is (-4) ; value of is 3 ; and value of r is 3.

Now since the noise of landing and taking off of the planes would be within the circle, hence we use less than equal to () sign instead of equal to sign.

Thus the general equation of noise of the planes can be given by the inequality
