Question

A body moves 180 degrees from point A to point B in a semi circle. The diameter of the semi circle is 2m. Calculate the distance traveled between point A and point B.

C = pi * d
= 3.1416 * 2m
= 6.283
= 6.283/ 2
= 3.141
ANS = 3.141
Is this done correctly??

Answer 1

C = pi * d
= 3.1416 * 2m
= 6.283
distance= 1/2 C =
= 6.283/ 2
= 3.141
ANS = 3.141
