1.	A man started from A and ends from D of o roding 21 m find distance and displacement
Answer» tion:The RADIUS of the circle= r(i) When it completes half circle:-(REFER to Image 1)Distance= 2circumference = 22πr Distance= πrDisplacement= r+r=2r(ii) When it completes 3/4 th of the circle:-The distance covered= 43 (circumference)⇒ 43 (2πr)= 23 πrThe displacement= AB (Refer to Image 2)By USING pythagoras theoremAB 2 =r 2 +r 2 ⇒AB 2 =2r 2 ⇒AB= 2 rDisplacement= 2 rDistance= 23 πr
