Answer:
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

Answer: 20</h3>
Explanation:
For any rectangle, the diagonals are the same length.
AC = BD
7x-35 = 3x+45
7x-3x = 45+35
4x = 80
x = 80/4
x = 20
It wouldn’t be 3.6ft because that’s how long the adult’s shadow is. It also couldn’t be 4ft because, it wouldn’t make sense for the child to be taller. I think 2.6ft is the best choice .
