Determine the geographic coordinates of St. John's (NL) and Papeete (Tahiti). Calculate the angular distance (in degrees and radians) and the distance in km between the two cities.

Here, geographic coordinates of

St. John's (NL) is latit

The angular distance is 100o

To covert it into radians,

1o = pie / 180o = 0. 0174444 radians

therefore,

100o = ?

multiply 100 with 0. 0174444 we get,

= 1. 7444 radians

Now we have a formula to calculate the distance between these two cities.

Let y is the distance between two cities

Therefore,

Y = (x/360) x 2 x pie x R

Here,

x = angular distance between the cities.

pie = 3. 14

R = radius of earth = 6371km

Hence, by putting these values in the above formula we get,

Y = (100/360) x 2 x 3. 14 x 6371

= (0. 277777) x 40009. 88

= 11113. 82 km
