While the earth's orbit (path) about the sun is slightly elliptical, it
can be approximated by a circle with a radius of 93,000,000 miles.
a) How far does the earth travel in one orbit about the
sun? That is, what is the approximate circumference of the earth's path?
b) Approximately how fast is the earth traveling in its orbit in space? Calculate
your answer in miles per hour.​

The circumference= 186000000Ï€ miles and the speed or the earth is 7750000Ï€ miles per hour.

Step-by-step explanation:

Radius (r) = 93000000 miles

a) circumference= 2Ï€r

= 2Ï€(93000000) miles

= 186000000Ï€ miles

b) speed = distance / time

Here distance is the circumference and time is 24hrs because if the earth completes 1 revolution around the sun in 24hrs.

Speed = 186000000Ï€/24

= 7750000Ï€ miles per hour

a. The circumference should be 186000000Ï€ mile

b. The speed of the earth should be 7750000Ï€ miles per hour.

Calculation of the circumference & speed of the earth:

Since the radius is 93000000 miles

a.

So, here the circumference is

= 2Ï€r

= 2Ï€(93000000) miles

= 186000000Ï€ miles

b) Now the speed is

speed = distance ÷ time

Here the time should be 24 hours

So,

Speed = 186000000π  ÷ 24

= 7750000Ï€ miles per hour
