A contractor is building the base of a circular fountain. On the blue print, the base of the fountain has a diameter of 18 cm. Find the area of the fountain
A: 317.11 cm²
B: 254.57 cm²
C: 113.09 cm²
D: 1017.88 cm²
Radius = Diameter/2
18/2=9 cm
Area of a circle = πr²
Area = (22/7)×9²
Area = 254.57 cm²
