Question

i tried doing this on my calculator but i keep getting the wrong answer..can someone try it on theirs and tell me what they got? thanks

Substitute the period in seconds, T = 86,400 s, the gravity constant G = 6.67 multiplied by 10-11 kg-1 m3/s2, and the mass of the Earth, ME = 5.98 multiplied by 1024 kg. Solve for r.

T^2=((4pi^2)/(GM_E))r^3

Answer 1

I got r = 9.10x10^14 meters.

A correction to the question above is
ME = 5.98x10^24 Kg not 5.98x1024 Kg

Maybe that's where the mistake is?

Hope that helps!
