Question

Given the equation for a circle, (x-h)^2+(y-k)^2=r^2, please define h, k and r.

Answer 1

In the equation for a circle, h represents the x-coordinate of the center, k represents the y-coordinate of the center, and r represents the radius.

Step-by-step explanation:

In the equation for a circle, (x-h)²+(y-k)²=r², h is the x-coordinate of the center of the circle, k is the y-coordinate of the center, and r is the radius of the circle.

For example, if the equation is (x-2)²+(y+3)²=5², the center of the circle would be (2,-3) and the radius would be 5.

Answer 2

see explanation

Step-by-step explanation:

given the equation of a circle in standard form

(x - h )² + (y - k )² = r² , them

(h, k ) are the coordinates of the centre and r is the radius
