An artificial satellite is moving in a circular orbit of radius \(42250\ km\). Calculate its speed if it takes \(24\ hours\) to revolve around the earth.

The formula to calculate the circumference of the circle is,

\(2 \times \pi \times D\)
\(\pi \times r\)
\(\frac{\pi}{D}\)
\(2 \times \pi \times r\)

Circumference of the orbit \(=\) \(km\)

Speed of the orbit \(=\) \(km\ h^{-1}\)

(Note: Enter your answers with one decimal place)
