Which of the following is the equation for a circle with a radius of r and center at (h, v)? a. (x + h)2 + (y + v)2 = r2 b. h2 + v2 = r2 c. (x - h)2 + (y - v)2 = r2 d. (x - v)2 + (y - h)2 = r2

Step-by-step explanation:

Hi There,

1. The Circle formula in its standard form is given by:

2) This coordinates a, b  are the Center coordinates of the Center, a point distant from the circumference by the radius.

3) Because we can find derive this formula from that. (Check the graph below)

There's a point P(x,y) whose distance to C(h,v) is the radius, we need to calculate it numerically:

4) Hence, as the Center has its coordinates C(h,v) then its circle formula is:
