Raduis of earth = 6400,
ht abve earth= 36000,
Total ht of Satlte from centre of earth = 6400+36000=42400km,
Distance traversed = perimeter=2πR = 2*3.14*42400.
Time= 24 hrs.
Speed= Distance/Time= (2*3.14*42400)/24 km/hr.

For a geosynchronous satellite the time period = 24 hrs.
Total height from the center of the earth = (36000 + 6400) = 42400 km.
Hence velocity = (2*pi*42400) km/24 hrs = 11100 km/hr.
Total height from the center of the earth = (36000 + 6400) = 42400 km.
Hence velocity = (2*pi*42400) km/24 hrs = 11100 km/hr.

Almost circular orbit so total distance is parameter of circle.
V=S*T
V=S*T

Why 11100?
