Apple estimates that 2.8 million square feet of the building is used for office space. Is their estimate reasonable? Below is the floor plan (each floor has a similar floor plan). Only the blue area is office space. Justify your response.

The estimate that 2.8 million square feet of the building is used for office space is not reasonable
From the plan, the width of the building is:
Width = 230 feet
The building has a circular area, and it has four floors
So, the estimate of the building area is:
Area= 4πR²
So, we have:
Area= 4 * 3.14 * 230²
Evaluate
Area= 664424
The above value cannot be approximated to 2.8 million
Hence, the estimate used for office space is not reasonable
