Question

Since the Earth is a 'sphere' lines of Latitude and Longitude form circles. A circle has 360 degrees. Circumference is typically measured using the formula [Pi * 2r], But, if you are given one degree's distance, you can simply multiply that distance by 360. Calculate the Earth's circumference at the following latitudes. (Show Work) a. 1 degree = 27.66 miles at the Arctic/Antarctic Circles b. 1 degree = 63.47 miles at the Tropic of Cancer/Capricorn The circumference of the Earth at the Equator is 24, 902 miles. How many miles are in 1" of longitude at the Equator? Remember the Equator is a circle and a circle has 360 degrees.

Explanation / Answer

Answer- it given that 1 degree at Arctic/ Antarctic circle represent 26.77 miles

for calculating the circumference , it the distance is given in degree then we have to multiply by 360

the circumference of Arctic/ Antarctic circle = miles in 1 degree*360 = 26.77*360 = 9637.2 miles = 15509.57km

given - 1 degree at Tropics of Cancer/ Capricorn represent 63.47miles

for calculating the circumference , it the distance is given in degree then we have to multiply by 360

so the cicumference of Tropic of Cancer /Capricorn circle is = miles in 1 degree*360= 63.47*360 = 22849.2 miles = 36772.2 km

answer- given - circumference of Equator is = 24902 miles

so the miles in 1 degree in equator will be = circumference of equator/ 360 = 24902/360 = 69.1 miles
