Radha takes 5 rounds around the edge of a circular ground with diameter 42 m. Find the distance she covers and the time she takes at the speed of 6 km per hour.
Distance covered = 5(pie*d)
= 5(22/7*42)
= 5(22*6)
= 5(132)
= 660 m
Time = Distance/Speed
= 660/6
= 110 s
= 5(22/7*42)
= 5(22*6)
= 5(132)
= 660 m
Time = Distance/Speed
= 660/6
= 110 s
