The distance between two places on Earth is 64Kilometers. Find the angle subtended by the arc joining these two pointsnat the center of the earth nearest to Seconds. Radius of Earth is 64000Kilometers.
------------------------------
I think the Earth's radius is 6400 km, not 64000
-----
The circumference of the Earth is 2*PI*6400 km (that's for all 360 degrees)
The angle subtended by 64 km is 360*64/(2*PI*6400)
= 0.57296 degrees
