A huge circular arc of length \( 4.4 \, \text{ly} \) subtends an angle ‘\( 4s \)’ at the centre of the circle. How long it would take for a body to complete \( 4 \) revolution if its speed is \( 8 \, \text{AU per second} \)?
Given:
\( 1 \, \text{ly} = 9.46 \times 10^{15} \, \text{m} \)
\( 1 \, \text{AU} = 1.5 \times 10^{11} \, \text{m} \)
