According. to me,The circumstance of earth is 25000 miles.Thus the option no.b is the correct answer.
if we are in kilometres we would find that the circumference of earth is
40075 kilometers.
The greek geographiest Eratothenes
was the first one
to calculate it

Option b is correct - 25,000 miles (approximately).
The circumference of earth is 24,901 miles or 40,075 kilometres.
The circumference is calculated by using the formula for calculation of circumference of a sphere, which is 2πRadius.
Radius of the earth is 6371 kilometres. Hence the calculation will be as follows:
2 x 3.14152 x 6371 = 40,075 (rounded off)
If the circumference were to be measured from pole to pole, the measure would be slightly less. The reason for this is because, the earth has a slight bulge around the equator due to it constant rotation.
