Question

The equation of the circle with center (3, -2) and radius 7 is (X blank) + (y blank)

Answer 1

Answer:

$(x - 3)^{2} + { (y + 2)^{2} = 49$

Step-by-step explanation:

Center of the circle = (3, - 2) = (h, k)

Therefore, h = 3, k = - 2

Radius r = 7

Equation of circle in centre radius form is given as:

$(x - h)^{2} + {(y - k)}^{2} = {r}^{2} \\ \therefore \: (x - 3)^{2} + { \{y - ( - 2) \}}^{2} = {7}^{2} \\ \red{ \boxed{ \bold{\therefore \: (x - 3)^{2} + (y + 2)^{2} = 49}}}$

Answer 2

Answer:

Step-by-step explanation:

(x-3)^2 + (y+2)^2 = 7^2
