Question

.An ant is walking
on the edge of a wall of radius
3m. After completing two or a
half round find the (a) distance and (b) displacement made
by the ant.​

Answer 1

Answer:

Distance= 2.5 × the circumference =

$2.5 \times 2\pi \times r$

= 5/2 × 2× 3.14 × 3=47.1m

After covering two and a half rounds, if starting from x, we will reach at point y. And the shortest distance between x and y will be the diameter.

So, displacement=2r=2×3=6m
