First you find the circumference... 2pi*r... and then you multiply that by 2.125. To find out the total amount of meters that the man walks!
We are given radius of circle as 4m.
Now if a man walks around a circle means we are considering the circumference here.
Circumference of circle can be found with the formula:
[tex] Circumference = 2* \pi *r [/tex]
Where r = radius of circle and pi = 3.14
plugging these values in the formula ,
[tex] Circumference = 2* 3.14 *4 [/tex]
Circumference = 25.12 m
Now distance covered by man when he walks around the circle once = 25.12m
distance covered by man when he walks around the circle 2.125 times = 25.12 *2.125 = 53.38 m
Answer : 53.38 m
