A man riding a bicycle completes one lap of a circular field along its circumference at the speed of 79.2km/h in 2 min 40 s What is the area of the field ?
Circumference of circular field = Distance covered by cyclist in one lap = (79.2*1000)/3600 * 160 = 3520 m
Hence, radius = 560 m
Area of the field = $$985600 m^{2}$$
Therefore, option A is correct.
