If Jaime must paint a 16-inch wide stripe around a water tank with a diameter of 150 feet, how long will the stripe be?

400 feet
471 feet
300 feet
525 feet

The correct answer is: 471 feet

To determine the length of the stripe around the water tank, we need to calculate the circumference of the tank. The circumference can be found using the formula: Circumference = π × diameter In this case, the diameter of the water tank is given as 150 feet. Plugging this into the formula gives: Circumference = π × 150 feet ≈ 3.14 × 150 ≈ 471 feet The width of the stripe does not affect the calculation of the length around the tank; it is simply along the circumference. Thus, the length of the stripe that Jaime must paint around the water tank is approximately 471 feet. This makes option B the correct answer. The understanding of how to calculate the circumference is crucial for numerous maintenance tasks involving round structures.
