Answer:
53.8 mi^2
Step-by-step explanation:
First we need to determine the radius of the crater. The circumfence formula is C = 2(pi)r, and here C = 26 miles. Thus,
26 mi = 2(pi)r, so that
26 mi
r = ------------ = 4.13 miles
2pi
Then the area of the crater is A = (pi)r^2, or:
A = 3.14(4.13 mi)^2 = 53.8 mi^2
