1. distance = √((x₂-x₁)²+(y₂-y₁)²)= radius of the circle.

distance = √((4-(-3))²+(5-(-2))7²) = √98

2. (x-k)²+(y-h)²=r² center (-3,-2) which is (k,h)

(x-(-3))²+(y-(-2))²= (√98)²

(x+3)+(y+2)² = 98 is the equation

Answer:

B.  (x + 3)^2 + (y + 2)^2 = 98

Step-by-step explanation:

(x + 3)^2 + (y + 2)^2 = 98

r =(sqroot)   (x − h^)2 + (y − k)^2

r =(sqroot)   (4 − (−3)^2 + (5 − (−2)^2

r =  (sqroot) 7^2 + 7^2

r =  (sqroot) 49 + 49

r =(sqroot)   98

x^2 + y^2 = r^2

(x − (−3)^2 + (y − (−2)^2 = (sqroot) ( 98)^2

(x + 3)^2 + (y + 2)^2 = 98

Answer:

r = √( s/4π)

Step-by-step explanation:

s = 4πr²

s/4π = 4πr²/4π

r² = s/4π

√(r²) =+/-√( s/4π)

r = √( s/4π)     Because r is a radius of the circle , it should be positive.
