2) There is a circular pond with a path along its boundary
A man completes a round on the edge of the path taking 220 steps
each 50 cm long The diameter of pond is_____ m
Distance travelled around the pond = number of steps * length of
step = 220 * 50 = 11000 cm = 110 m
i e perimeter of the circular pond = 110 m
But the perimeter of a circle = pi * diamater ( 2 * pi * radius
= pi * diameter as diameter = 2 * radius)
pi * diameter = 110 m
22/7 * diamater = 110
diameter = 110 * 7 / 22 = 5 * 7 = 35 m
So the diameter of pond is 35 m
