What is the equation of a circle with center (8,6) and radius 5?
O A. (x-8)2 + (y- 6)2 = 25
O B. (x+8)2 + (y + 6)2 = 5
O C. (x+8)2 + (y+ 6)2 = 25
O D. (-8)2 + (-6)2 = 5

Respuesta :

Answer:

A. (x-8)^2 + (y- 6)^2 = 25

Step-by-step explanation:

The formula for calculating the equation of a circle is  (x-a)^2 + (y- b)^2 = r^2

substituting the values of a=8, b=6, and r=5

The equation of the circle becomes  (x-8)^2 + (y- 6)^2 = 25
