Once in Chicago, Debbie plans to visit the Willis Tower; the 2nd tallest building in the Western Hemisphere. Its height is 818% of the height of the tallest building in the Western Hemisphere, One World Trade Center in New York. If the One World Trade Center is 1,776 feet tall, how tall is the Willis Tower (to the nearest foot)?

a) 14,510 feet
b) 14,520 feet
c) 14,530 feet
d) 14,540 feet

Answer 1

To find the height of the Willis Tower, multiply the height of the One World Trade Center by 8.18. After calculating, the Willis Tower is approximately 14,532 feet tall, rounded to the nearest foot.

Step-by-step explanation:

The question is asking us to calculate the height of the Willis Tower in Chicago, knowing that it is 818% of the height of the One World Trade Center in New York, which stands at 1,776 feet tall. To find the height of the Willis Tower, we simply multiply the height of the One World Trade Center by 818% (or 8.18 as a decimal).

Here is the step-by-step calculation:

• Convert 818% to a decimal by dividing by 100: 818 ÷ 100 = 8.18.
• Multiply the height of the One World Trade Center by the decimal: 1,776 feet * 8.18 = 14,531.68 feet.
• Since we need the height to the nearest foot, we round 14,531.68 to 14,532.

Therefore, the Willis Tower is approximately 14,532 feet tall.
