The radius of Earth is 6,371 kilometers.
\n" ); document.write( " A space shuttle orbits 315 kilometers above the surface of Earth.
\n" ); document.write( "Find the circumference equal to the shuttle's path
\n" ); document.write( "C = 2*pi*(6371+315)
\n" ); document.write( "C = 42,009.4 km
\n" ); document.write( ":
\n" ); document.write( " The space shuttle completes 240° of a revolution around Earth in one hour
\n" ); document.write( "\"240%2F360\" * 42009.4 = 28,006.25 km/hr is the speed of the shuttle\r
