That would be the area of a circle of radius 12 miles
= pi r^2 = 452.4 square miles to nearest tenth.
Answer:
Step-by-step explanation:
u need to multiply.
<span><span>A = P(1-r)^t
</span><span>
A = 3900(1-0.08)^10
A = 3900(0.92)^10 </span></span><span><span>
A = 3900(0.434388454)
A = 1694.11
1694 square km</span></span>
