Question

if man walks around a circle 2.125 times, how many metres did he walk if the radius of the circle is 4m

Answer 1

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:

Where r = radius of circle and pi = 3.14

plugging these values in the formula ,

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
