Question

the distance the earth travels in one year equals the circumference of its orbit TRUE or FALSE?

Answer 1

i think it is True

Answer 2

b/c the circumference of a circle is equal to 2*pi*Radius

The average distance from the Earth to the Sun is 149,597,890 km. Therefore in one year the Earth travels a distance of 2*Pi*(149,597,890)km. This means that the velocity is about:

velocity=2*Pi*(149,597,890)km/1 year

and if we convert that to more meaningful units (knowing there is 365 days in a year, and 24 hours per day) we get:

velocity=107,300 km/h (or if you prefer 67,062 miles per hour)

So the Earth moves at about 100,000 km/h around the Sun (which is 1000 times faster than the speeds we go at on a highway!)

Answer 3

True. The circumference of an ellipse is the path around the ellipse just like the circumference of a circle. The earth's path around the sun is an ellipse.

thank you so much
