Answer 1

Step-by-step explanation:

see athlete covered three and half round it means we have to considered only half round because 3 round are completed and displacement will be zero....

so, circumference of half circle = πr

so, 22/7×28

88m is your answer..

Answer 2

Step-by-step explanation:

distance = π×diameter

= 22/7*56

=22*8

=176

distance covered in three and half round

=176*3+176*0.5

=528+88

=528

athlete covered half of the circular track so it's

displacement is equal to its diameter

so it'd answer is 56
