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.

where is the questions

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
