The area of a circular field is 154 m2. Find the time taken by an athlate to complete2 rounds if she is jogging at the rate of 5 km/hr.



Area of the field=π r^{2} =154 m^{2}
 r^{2} =7/22*154=7*7
circumference of the field=2πr=2*22/7*7=44m
since she has to jog 2 rounds=2*44=88m=she has to jog
she takes 1 hour for jogging 5000m
the time taken=88/5000*60=1.056min
