Answer:

12.00, 37.70

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.
