Radius of the circular orbit, r= 42250 km
Time taken to revolve around the earth, t= 24 h
Speed of a circular moving object, v= (2π r)/t
=[2× (22/7)×42250 × 1000] / (24 × 60 × 60)
=(2×22×42250×1000) / (7 ×24 × 60 × 60) m s-1
=3073.74 m s -1

Hey there!
Given,
Radius (r) = 42250 km
Time (t) = 24 hours
Distance will equal to perimeter of the orbit
= 2πr
= 2π * 42250
Speed of artificial satelite
= 2π * 42250/24
= 11059 km/h
Hope It Helps You!
