Which of the following is the equation of a circle with a radius of 2.5 and its center at (4,- 3)?


(x - 4)^2 + (y + 3)^2= 2.5


(x - 4)^2 + (y + 3)^2= 6.25


(x - 4)^2 + (y- 3)^2= 2.5


(x - 4)^2 + (y - 3)^2= 6.25

Hello,

Answer B

(x-4)²+(y+3)²=2.5²=6.25


Answer:

(x - 4)^2 + (y + 3)^2= 6.25

Step-by-step explanation:

To solve this problem, we need to remember the formula to find the equation of a circle of radius r and center in (h,k): \((x-h)^{2} +(y-k)^{2} = r^{2}\)

Now we need to substitute the values given in the problem.

We have r = 2.5, h = 4, r = -3

\((x-h)^{2} +(y-k)^{2} = r^{2}\\(x-4)^{2} +(y-(-3))^{2}=2.5^{2}  \\(x-4)^{2}+(y+3)^{2}  =6.25\)

Therefore, the correct option would be B)
