Answer:
12.00, 37.70
Step-by-step explanation:
Area of a circle is:
A = πr²
We know A = 113.1 ft², so:
113.1 = πr²
r² = 36.00
r = 6.00
The diameter is double the radius, so:
d = 2r
d = 12.00
The diameter is 12 feet.
The circumference is:
C = 2πr
We found that r = 6 ft, so:
C = 2π (6)
C = 37.70
The circumference is 37.70 ft.
