Question

The planet takes one year to revolve around the Sun. Assume that a year is 365 days and the path of the Earth around the Sun is the circumference of a circle of radius 150 000 000 km.
a) Calculate the distance travelled by the Earth in one day.

Answer 1

R=150 000 000 km
π≈3,14
O-obwód (the path of the earth around the Sun)
L-dystans przebyty w ciągu 1 dnia (distane travelled by the earth in one day)

O=2πr
O=2 * 3,14 * 150 000 000 km
O=942 000 000 km

d=942 000 000 km : 365 = 2 580 821,918 km

Odp. Dystans jaki pokonuje Ziemia w ciągu dnia (a właściwie doby)
to 2 580 821,918 km.
