There is a circular Park in front of a shopping mall whose radius is 20m. There is a gravel path of uniform width the 2m around the park. Find :A person take 5 round of the circular Park. What distance he cover.

Answer 1

Assuming that he walks the middle if the path, then his radius = 21m

Circumference = 2πr

5C = 5(2πr)

Insert values and calculate.

Answer 2

Radius=20m
Distance covered by the person =5×circumference of circle
=5×2×3.14×30
=200×3.14
=628sq.cm

Answer 3

It's 20 not 30

Answer 4

Very bad nothing is there in this

Answer 5

Man walks 5 rounds around it.
R=20cm
So, circumference would be =
2×3.14×20×5
=628 meters
