(x+8)^(2) + (y+9)^(2) = 169
(x+8)^(2) + (y+9)^(2) = 13^2
h = -8
k = -9
r = 13
answer
A. center (-8,-9)
radius = 13
--------------
(x-7)^2 + y^2 = 225
(x-7)^2 + y^2 = 15^2
h = 7
k = 0
r = 15
answer
B. center (7,0)
radius = 15

Since 3 out of 5 doctors (60%) use brand X, solve for 60% of 2,000, which is 1,200 doctors.
Step-by-step explanation:
There are four quarter circles, each with radius 9 ft. Together, they form a full circle. There are also four squares, each with side length 9 ft.
A = πr² + 4s²
A = π (9 ft)² + 4 (9 ft)²
A ≈ 578.469 ft²
