Question

The surface area of the top surface of the water in a circular swimming pool is about 206 square feet. Estimate the radius of the pool, to the nearest foot.

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

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

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
