Answer:
Umm is it; 0.0004985064 [tex]ft^{2}[/tex]
Step-by-step explanation:
A = [tex]\pi r^{2}[/tex]
because you said the radius is 0.00012 x 105. so
0.00012 x 105 = 0.0126
so 0.0126 would be the raduis.
0.0126 x 0.0126 = 0.00015876
0.00015876 x 3.14 ([tex]\pi[/tex]) = 0.0004985064
I hope this helped.
