Answer:

r = 4 units

Step-by-step explanation:

From the question it is not clear that what you want to ask. But as per me you are interested in finding the radius of the circle.

Since, circle is touching y-axis at has a center (-4, 8) so it's radius will be equal to the x-coordinate.

Here, x - coordinate is - 4

Since radius is a non negative number.

So, r = 4 units

What is the center and radius of the equation (x-8)^2 +(y+6)^2=13

tatyana61 [14]

Answer:

see explanation

Step-by-step explanation:

the equation of a circle in standard form is

(x - a)² + (y - b)² = r²

where (a, b) are the coordinates of the centre and r is the radius

(x - 8)² + (y + 6)² = 13 is in this form

with centre = (8, - 6) and r = $\sqrt{13}$
