Question

Find the equation of the circle with center at (-1, 3) and radius of 4.

Answer 1

Answer:

Given that:

Radius, r = 4, and center (h, k) = (-2, 3).

We know that the equation of a circle with centre (h, k) and radius r is given as

Now, substitute the radius and center values in (1), we get

Therefore, the equation of the circle is

Now, simplify the above equation, we get:

Thus, the equation of a circle with center (-2, 3) and radius 4 is

Step-by-step explanation:

Answer 2

Answer:

That is the Equation of the circle. (x-a)^2 + (y-b)^2 = r^2 is the equation of a circle which has center point (a,b) and radius r. So in this question (2,-3) is the center and r=4.
