Goobada ee goobaabin waxay la mid tahay 2πr halka r ku taal raadiyow. On the Dhulka, ah goobada ee goobta at a siiyey loolka waa 2πr (cos θ) halka θ ku yaal loolka iyo r waa raadiyaha Dhulka dhulbaraha.

Sidoo kale, waa maxay wareegga dhulka ee latitudes kala duwan?

Latitude At tirarka (90°):

1° ee Latitude (1/360th of the Earth's Polar wareegga) waa 111.6939 km (69.40337 mayl)
1" (1 ilbiriqsi) ee Latitude (1/3600th ee 1 °) waa kaliya 31.0261 m (101.792 cagood)
0.1" (1/10th labaad) ee Latitude (1/36000th ee 1 °) waa kaliya 3.10261 m (10.1792 cagood)

Marka labaad, waa maxay wareegga dhulka ee loolka 40 degree? Wareega Dhulka 40-deg Waqooyi = 30,600 kiiloomitir.

Tan ka sokow, waa maxay wareegga dhulka ee loolka 45 darajo?

Dhulbaraha, dhexroorka dhulka qiyaas ahaan waa 12,760km waxayna si tartiib tartiib ah hoos ugu dhacaysaa tiirarka waqooyiga iyo koonfurta. 12,760/2Cos45 = 6380/√2. Sidaa darteed, the wareegga dhulka oo ah 45°N = 2π6380/√2km, oo la mid ah: 28, 361.28km.

Waa maxay wareegga dhulka ee dhulbaraha?

Isticmaalka cabbiradaas, wareegga dhulbaraha ee dhulku waa qiyaastii 24,901 miles (40, 075 km). Si kastaba ha ahaatee, laga bilaabo cidhif-ilaa-cir - wareegga meridional - Dhulku waa 24,860 oo keliya miles (40, 008 km) agagaarka. Qaabkan, oo ay keento fiditaanka tiirarka, waxaa loo yaqaannaa spheroid oblate.
