Question

answer as far as step by step

Answer 1

pie r - 56

pie.28 - 56

87.9 -56
31.9 m
32 m
its (2)

Answer 2

Here the perimeter of the semicircle = (2*(22/7)*radius) /2

=(88*28/7)/2

=(88*4)/2

=352/2

=176

Now the diameter = 28*2=56

So the extra distance that we have to cover = 176-56 =120 meter
