If the area of a circle is 58 square feet, find the circumference. a. 22.35 ft. b. 26.99 ft. c. 4.25 ft. d. 42.5 ft.

  B.  26.99 ft.

Step-by-step explanation:

The formulas for circumference (C) and area (A) are ...

  A = πr²

  C = 2πr

Solving the area formula for r, we get ...

  r = √(A/π)

Substituting this into the circumference formula gives ...

  C = 2π√(A/π) = 2√(πA)

For the given circle, the numbers are ...

  C = 2√(3.14×58 ft²) ≈ 26.99 ft
