r= 7/16 in
1 in = 2 miles

r = (7/16) in * (2 miles / 1 in)
r = 7/8 miles

A = pi * r^2
A = ~3 * (7/8)^2
A = ~3 * 49/64
A = ~ 147/64
A = 2.something

Only one answer is in this area: B.

In this problem, you need to convert photo scale into the actual sclae. i.e. the radius of photo to the radius of actual place in the air.
s0, 7/16*2=14/16.
knowing the formula of the area of the cirlce - (pi)r^2
the area will be - 196/256(pi) ( pi=3.14 so it would be approximately 3)
after simplification - 49/64*(pi), round both numerator and denominator to the closest number.
50/65*3=10/13*3=30/13, approximately 2.3 smth.
so the answer should be b.
