Question

If a person walks a circular park at a speed of 15 km per hour for 2 hours, what is the perimeter of the park?​

Answer 1

Answer:

We know that circumference(perimeter) of circular path is 2πr and speed in circular path is

S=2πr/t.

So, S=2πr/t

15 =2πr/2

2πr=30km

This is your answer ..
