about 14 feet

about 11 feet

about 10 feet
im giving 82 points plzzzzz i need the help hurry i got 2 min

about 8 feet

Answer 1

Answer:

R² =206/π ==>R² = 206/3.1459==> R² =65.5 ==> R=√65.5 ≈8 ft

Step-by-step explanation:

Answer 2

The area of a circle = πR², where π=3.1459... & R = Radius

The area of our circle  ≈ 206 ft² = πR², Solve for R²:

R² =206/π ==>R² = 206/3.1459==> R² =65.5 ==> R=√65.5 ≈8 ft
