Answer:
Area: 28.26ft², Circumference: 18.84ft
Step-by-step explanation:
Area of a circle: πr²
Circumference of a circle: πd (or 2πr)
Since the diameter is 6ft, then the radius is half of that, which is 3ft. This means that our area is:
πr²
π(3)²
π(9)
9π
9(3.14)
28.26ft²
Our circumference is:
πd
π(6)
6π
6(3.14)
18.84 ft
