Q.) A horse take seconds to complete a round around a circular field. If the speed of the horse was 66 m/sec, then the radius of the field is,[Given ]
(a) 25.62 m
(b) 26.52 m
(c) 25.26 m
(d) 26.25 m
Speed of the horse was 66 m/sec.
total distance travelled in seconds = X 66 = 165 metres
This will be equal to the circumference of the Circle.
=> = 165
=> r = = 26.25 m
Hence , Option(d)
