$\"\"$

Circumference of orbit is given by $\"\"$ .

$\"circumference$

$\"\"$ (Substitute $\"\"$ )

$\"\"$ (Use a calculator to multiply) $\"\"$

Time required for revolving around the sun $\"\"$ .

$\"circumference$

Distance to travel = circumference of Earth’s orbit = $\"\"$

Speed/velocity of earth = 66,698 miles/hour

$\"\"$ (Substitute the values)

$\"\"$ (Use a calculator to evaluate) $\"\"$

24 hours = 1 day. (A day has 24 hours)

Divide the period of revolution by 24,

$\"\"$

= 1 year (A year has 365 days) $\"\"$

It takes 1 year for Earth to revolve around the Sun.
