please answer this question with a proper solution and pls no scam answers.if you don't know leave it​

Answer 1

Answer:

(d) 14m

PLEASE MARK AS BRAINLIEST!!

Step-by-step explanation:

After 1/2 revolution he reaches the other side of the circle.

Displacent is the shortest distance between the starting and ending point. In this case the displacement will be the diameter of the circle.

Radius = 7m

Diameter = 7×2 = 14m

Therefore, the displacement is 14m

Answer 2

Answer:

14

Step-by-step explanation:

radius =7m

displacement =diameter=2*7=14
