Question

A body travels 25% of circumference of a circular path having radius ""r"" cm.

Answer 1

Answer:

distance travelled =25/100 × 2pi r

= pi r/2

Answer 2

Ans: Distance: 25% means 1/4 of the total distance

{Circumference of the circular path = 2πr}

# 25% of circumference = 2×π×1/4 =πr/2

# distance is πr/2

Displacement so AB = √r^2+r^2 =√2r [ By pythagoreas theorem ]
