Question

When a boy completes 5 rounds around a circular pond, he covers a distance of 440m. i)Find the perimeter of the pond. ii)Find the diameter of the pond.

Answer 1

Step-by-step explanation:

distance covered by boy in 5 round=440 m

distance cover in 1 round =440/5 m=88m

distance cover in 1 round= circumference(perimeter) of circle=88m

2πr= 88m

2*22/7*r=88 m

r=88*7/22*4

r= 7m

diameter= 2r= 2*7 m= 14m
