Ответ:
time taken t = 6.00 seconds
the time taken to cover half a round is 6.00 seconds
Explanation:
Given;
Speed of ant v = 11 m/s
radius of Circle r = 21 m
Circumference of a circle
c = 2πr
Half a turn d = c/2 = 2πr/2 = πr
Time taken to cover distance d( half a turn);
time = distance/speed = d/v = πr/v
Substituting the values;
time =(π×21)/11 = 5.997585975035 seconds
time taken t = 6.00 seconds
