Question

A boy runs half a round in a circular track of radius 7 m. calculate (a) distance covered
by the boy (b) displacement

Answer 1

Answer:

distance =7× 2×22/7×1/2 =22m

displacement = 2×radius = 2×7 14m

Answer 2

Answer:

Distance=22m and Distance=14m.

Explanation:

Given,

Radius=7 m

Distance= 1/2(circumference of the circle)

Distance=1/2(2πR)

Distance=1/2(2×22/7×7)

Distance=22m

Now displacement = 2R

Displacement=2(7)

Displacement=14m
