men walk in 1 round = πr

=22/7*140

=22*20

= 440m

Answer 2

Answer:

2640m

Step-by-step explanation:

Given :

Circle of radius = 140 m

Walks 3 rounds

To find :

meters men walk​

Formula :

$Circumference = 2 \pi r$ , $\pi = \frac{22}{7}$

Solution :

Man walks 3 rounds that means

distance will be 3 × 2πr

=> Distance = 6πr

$=> Distance = 6\times \frac{22}{7} \times 140 \\\\=> Distance = 6 \times 22 \times 20\\=> Distance = 2640 m$
