Question

Assuming that the the equilateral radius of the the earth is 3132.5 kilometre find the circumference of the equator

Answer 1

Circumference=2*Pi*r
=2*22/7*31325/10(km)
=2*22*447.5km
=19,690km

Answer 2

Answer:

19672.1 Km

Step-by-step explanation:

As we have given in the question, We have given the radius of the equator Which is=3132.5 Km

We need to find the circumference of the equator which is=$2\times3.14\times r$

So as we were given the radius all we need to do is just put the value of Radius in the above formula.

Therefore circumference=$2\times3.14\times3132.5=19672.1$

Therefore our final answer would 19672.1 Km is the circumference for the equator
