Answer 1

Answer:

this is the correct answer of this question

Answer 2

Answer:

Here is your answer

Given:-

speed of 10 km per hour.

radius 50 cm .

we have to find circumference of Circle

=>2πr

=>2×3.14×50

=>314cm

convert cm in km into cm

10 km = 1hr

1000000 cm = 3600 sec

Now

we find the time to cover 1 sec

1000000 cm = 3600 sec

$1sec = \frac{3600}{1000000} \times 314$

$314sec = 1.13sec \: (approx)$

The cycle take time of 1.13 sec to make a round of a circular field of radius 50 cm

Hope it helps you
