Answer:
3981 miles
Step-by-step explanation:
Circumference refers to the perimeter of circle . Let r be the radius of circle then it's circumference is given by where .
Here, circumference = 25,000 miles .
We need to find distance between the point on earth's surface and the centre i.e we need to find radius here .
Circumference =
On dividing both sides by 6.28 , we get
On rounding off the value of radius r , we get
So, distance between point on earth's surface and centre is 3981 miles .
