Math is wrong in foam applications calcs.

Use this

  if (diameter < 150) return 0.20;
  if (diameter <= 200) return 0.23;
  if (diameter <= 250) return 0.25;
  if (diameter <= 300) return 0.28;
  return 0.31;
}

function getTankArea(diameter) {
  const radius = diameter / 2;
  return Math.PI * radius * radius;
}

function calculateUpdatedFoamRates(tanks) {
  const result = {};

  for (const tankId in tanks) {
    const { diameter, material, location } = tanks[tankId];
    const rate = getUpdatedFoamRateByDiameter(diameter);
    const area = getTankArea(diameter);
    const foamGPM = area * rate;

    result[tankId] = {
      diameter,
      material,
      location,
      applicationRate: rate,
      surfaceArea: area.toFixed(2),
      foamGPM: foamGPM.toFixed(0)
    };
  }

  return result;
}

console.log(calculateUpdatedFoamRates(tankData));```

This will work out too ```
const tank = {
id: 101,
diameter: 200,
capacity: 100000,
location: "Dock 2"
};

function calculateFoamGPM(tank) {
let rate;

if (tank.diameter < 150) return 0.02;

else if (tank.diameter <= 200) rate = 0.23;
else if (tank.diameter <= 250) rate = 0.25;
else if (tank.diameter <= 300) rate = 0.28;
else rate = 0.31

let radius = tank.diameter / 2;
let area = radius * radius * Math.PI

let foamGPM = rate * area

return Math.round(foamGPM)
}
