Question

The distance covered by a body along a semi-circular path is 44 m. find The displacement
of the body is a ) 44m b) 14m c) 7m d)28 . find the correct answer and explain. I will mark as brainiest ​

Answer 1

Answer:

D) 28 m

Explanation:

The distance covered by the body = Length of Semi-Circular Path

                                                          = 44 m

Now,

$44 \ m = \frac{Area \ of\ whole \ circle}{2} \\\\44 \ m = \frac{2\pi r}{2} \\\\44 \ m = \pi r\\\\44 \ m = \frac{22 \times r}{7} \\\\r = \frac{44 \ m \times 7}{22} \\\\r = 14 m$

Displacement = Shortest distance between two points

                       = Diameter of the Semi circle

                       = 2 × radius

                       = 2 × 14 m

                       = 28 m
