Question

F. Solve the following numerical problems.
1. A man runs around exact half the circumference of a circular park of diameter 40 m.
What is the displacement of the man?
10 km​

Answer 1

628.57

Explanation:

I hope it works bcs displacement is22÷7×20×10

Answer 2

Answer:

22.85 is the displacement of a man

Explanation:

2×22/7×40/2= 125.71/2=62.85m

circumference of circle= 2πr

radius= 40m

half of circumference= 62.85m

distance of mam= 62.85-40=22.85m ( because the man has ran a distance equivalent to the radius of the circle due to which the radius of circle would be minus from the half of circumference of the circle.)
