A circular pond has a 90cm wide foot path
mans step=65.94cm
he took 400 steps
circuference of the path=26376cm
circumference= 44/7 * radius
26376=44/7 * radius
radius = 26376*7/44
=4196.18cm
this is the radius inclduing path
radius of the pond only = 4196.18-180
= 4016.18
mans step=65.94cm
he took 400 steps
circuference of the path=26376cm
circumference= 44/7 * radius
26376=44/7 * radius
radius = 26376*7/44
=4196.18cm
this is the radius inclduing path
radius of the pond only = 4196.18-180
= 4016.18

pls brainliest
it asked to do with the 3.14 but you have used the 44/7 method.
see 3.14 is nothing but 22/7
circumference of a cirle= 2 * 22*radius/7
so i directly wrote 44 /7 radius
understood???
oh ok thankz
