Answer:
136112
Step-by-step explanation:
since the outer circle is 25cm wider on one side, the radius of outer circle is 25 cm wider. (imagine rotating the green line to match with the pink line, you'll see the outer circle radius more clearly)
r of inside circle = 148.4/2 = 74.2
r of outside circle = 74.2 +25 = 99.2
the shaded region = A of outer circle - A of inner circle
=3.14(99.2)^2 - 3.14(74.2)^2
area of a circle is , I plugged in known values above^.
= 30899.6096 - 17287.7096 = 13611.9 (I definitely recommend a calculator)
rounded to nearest whole number = 13612
