Hey Friend ☺
Distance is equal to the circumference of semicircle
Circumference of circle = pie × r + d
= 2 × 3.14 + 28
= 6.28 + 28
= 34.28 cm
Displacement is the minimum distance from the starting point
Do the displacement is equal to diameter of circle
So ..
displacement = 28 cm
Hope it helps you ..!!
