Question

a fly buzzes four and a half times around kit yan’s head. the fly ends up on the opposite side from where it started. if the diameter of his head is 14 cm, what is the total displacement the fly travels? assume kit yan’s head is a sphere, which has a circumference of 2π*(radius). if you answer is not an integer, round it to the nearest tenths place (1st decimal place). ______ cm your answer

Explanation:

Step1: Define displacement concept

Displacement is the straight-line distance between start and end positions, following the shortest path between two points on a sphere (a straight line through the sphere, which is its diameter).

Step2: Identify given diameter value

The diameter of the sphere (head) is given as $14$ cm.

Step3: Confirm displacement equals diameter

Since the fly ends on the opposite side of the sphere from its start, the straight-line distance between these two points is exactly the diameter of the sphere.

Answer:

14 cm
