Area = pi * radius^2
radius = diameter/2 = 26/2 = 13 feet
Area = 3.14 * (13^2)
Area = 3.14 * 169 = 530.66 ft^2

Answer:
B. (x +4)² +(y +5)² = 64
Step-by-step explanation:
The equation for a circle with center (h, k) and radius r is ...
(x -h)² +(y -k)² = r²
Filling in your given values, you have ...
(x -(-4))² +(y -(-5))² = 8²
Simplifying, you get ...
(x +4)² +(y +5)² = 64 . . . . . . . matches choice B
