Question

A circular track has a radius of 500 m with AB as its diameter. If you move along the circular path, then calculate:

(a) total distance covered and the displacement, if you move along the circular path from A to B.​

Answer 1

Given

radius = 500m

Distance

circumference = 2πr

since from A to B (half circle)

Distance =πr = 500π m

Displacement

From A to B = diameter = 1000m

Hope this helps

Answer 2

$\huge \text{Question - }$

A circular track has a radius of 500 m with AB as its diameter. If you move along the circular path, then calculate:

(a) total distance covered and the displacement, if you move along the circular path from A to B.

$\huge \text{Answer - }$

GIVEN -

• Radius of the circular track = 500 m
• Diameter = AB

TO FIND-

• Total distance covered if you move along the circular path from A to B
• displacement covered if you move along the circular path from A to B

STEP BY STEP SOLUTION -

• Distance covered from A to B

$\sf :\implies Distance = \dfrac{ \cancel{2} \pi \: r }{ \cancel{2}}$

$\sf :\implies \dfrac{22 \times 500}{7}$

$\sf :\implies 1571.428 \: m \: (approx)$

• Displacement covered from A to B

$\sf :\implies Displacement = AB$

$\sf :\implies Displacement = 2r$

$\sf :\implies 500 \times 2$

$\sf :\implies1000$
