**Steve**, Friday, November 23, 2012 at 1:50pm8 hours at 1000km/hr = 8000km.

The circumference of the earth is roughly 40000km, so the trip was 1/5 of the way around, or 72°.

The plane is now at 72-36.8 = 33.2° south.

At that latitude, the east-west circumference is 33470 km

8000/33470 * 360° = 86°

so, the plane is now at 86-20.6 = 59.4° west

**Eniola**, Saturday, November 1, 2014 at 7:19amPerimeter of a sector = 2r +:)/360 * 2 * 22/7 * r Hence, 2*9+120/360*2*22/7*9= 18 +120 *2 * 22 *9/2520 =18 +47520/2520 = 18+18.86 = 36.86cm
