Question

A satellite sends signals from space to the regions which lie within the shaded portion of the Earth, as shown below.


If the radius of Earth is approximately 6000 kilometers, the part of Earth which receives signals from the satellite has an area of ________ square kilometers. Use π = 3.14.

Answer 1

i keep gettung 18849555 and i dont think thats right -__-

Answer 2

the area of that region would be (exposed) = 4 * pi * radius^2 (1- cos^2(60degrees))

Answer 3

so approximately 27135093026.1 ...if I did it right(:

Answer 4

I rounded..
