A 40 foot tall flag pole feet r from an observer subtends an angle of 1.75°

Question

Use the arc length formula to estimate r (the distance between the observer and the flag pole) to the nearest foot.

r ≈ ? feet

Answer 1

1310 feet, rounded off, and just an estimate, although close as the arc length is longer than the chord.

arc length = radius x angle if angle is measured in radians

arc length = radius x radians

1.75 degrees = about 0.03054 radians

r=40/.03 = 1310 feet roughly
