Which equation represents the general form of a circle with a center at (-2,-3) and a diameter of 8 units

Equation of circle is  (x + 2) ²+ ( y + 3)² = 4².

Step-by-step explanation:

Given  : a circle with a center at (-2,-3) and a diameter of 8 units.

To find : Which equation represents the general form of a circle .

Solution : We have given  center at (-2,-3) and a diameter of 8 units.

Radius = .

Radius =  .

Radius = 4 units.

Standard form of circle is  (x -h) ²+ ( y -k)² = r².

Where,  ( h, k) is center , r =  radius .

Plug center ( -2 ,-3) and  r = 4 .

 (x - (-2)) ²+ ( y - (-3))² = 4².

 (x + 2) ²+ ( y + 3)² = 4².

Therefore, Equation of circle is  (x + 2) ²+ ( y + 3)² = 4².

it is b)
