Question

There is a circular pond and footpath runs along its boundary. A man walks around it exactly once keeping close to the edge. If his step is 66 CM long and he takes exactly 400 steps to go round the pond, what is the diameter of the pond? ​

Answer 1

1. Find the circumference of the pond by multiplying the steps taken with the length of each step

2. Circumference= 2πr

3. You'll get the radius. Multiply that with 2 to get the answer

Answer 2

Answer : the diameter of the pond = 8400
