Question

The radius of a semicircular garden is 28 m how much more distance has one to cover from going from a to b on the circular path instead of going on diametrical path

Answer 1

one has to cover distance equal to the circumference of semi circle.
circumference of semi circle =
circumference of circle/2
= $2\pi r \div 2 = \pi r$
= 22/7 * 28
= 22 * 4
= 88 m
one has to cover 88 m to go from a to b using circular path
