The body travels in the circular path and it covers one circumference in 24 hrs.
So, the distance travelled = 2πr = 2π×42250
= 84500π km
speed = distance/time
= 84500π/24(84 500 * π) / 24
= 11 061.0241 km/hr
hope you understand the concept.

can you tell me
π = 3.14159265
22 / 7 = 3.14285714
it is not correct
and please mind your own buisness
beta tujhse bada hu ..age mai bhi .. experience mai bhi..knowledge mai bhi..amd qualifications mai bhi. samjh le kya difference hai dono mai..instead of proving me wrong
ok I am wrong
but we always take the value of pie as 3.14 or 22/7
so for the simplicity we have taken it as 22/7
we are also taught to take take the value of pie as 22/7 so why do we take it as 3.14159265
