Answer:
There are 21 flares there
Step-by-step explanation:
Firstly, we need to know how large the circle is
To calculate how large the circle is , we need to know what the circumference of the circle is
Mathematically, the circumference of a circle = pi * D
where D is the diameter of the circle and pi = 22/7
Thus, the circumference of the circle = 22/7 * 10.5m = 33m
Now, to know the number of flares, we divide the circumference of the circle by the the distance between the flares
That would be 33/1.57 = approximately 21
