Question

A person travels on a semi-circular track of radius 49 m. If he starts from one end and
reaches the other end, calculate the distance travelled and the displacement of the
person.
​

Answer 1

Explanation:

here

radius=49m

total distance=circumference=2πr

=2×22/7×49

=308m

displacement=diameter=2r

=2×49

=98m

Answer 2

Answer:

Given ,

radius = 49 m

Displacement = shortest distance between two points .

Displacement = 2r

                       = 98 m

Distance = 2πr

               = 2 × 22/7 × 49

               = 308 m
