Final answer:
The area of a circle with a radius of 0.00012 X 10^5 ft, calculated to two significant figures, is approximately 450 sq ft.
Step-by-step explanation:
The question is asking for the area of a circle with a radius of 0.00012 X 105 ft. Before we can calculate the area, let's determine the actual radius. The radius is obtained by multiplying 0.00012 by 105, which simplifies to 12 ft.
Now, we can calculate the area of the circle. The formula for the area of a circle is πr2 where 'r' is the radius. Substituting the values gives, Area = π * (12 ft)2.
So the area of this circle, keeping in mind that this should be to two significant figures as the radius is given to two significant figures, is 450 ft2. This is a simplified and approximated value due to the limitation of significant figures.
