For each of the following, enter your answers using scientific notation with 4 significant figures. For example, 1,234,000 would be written as 1.234e6. Use the value of 1 Earth year = 365.26 days, if needed for your conversions.

Saturn orbits the Sun once every 29.456 Earth years. Assuming the orbit of Saturn is circular,Through what angle (in radians) does a line from the center of the Saturn to the center of the Sun sweep in one day?

I found that the angle swept out in one day is 5.840×10Saturn is approximately 1,427.0 million km from the Sun. How far does Saturn travel in one day?^{-4}rad

I found that Saturn travels8.334×10What is the speed of Saturn, in km/hr, in its orbit around the Sun?^{5}km in one day

-Here's where I'm stuck, I beleive that this is going to be the linear velocity in the fomula v=rw1,427.0 million km or 1427000000 or 1.427x10^9
