Answer:

Circumference:   C = 7.5π m.  This is approximately 23.56 m

Total fencing cost:  $215.76

Step-by-step explanation:

Ashton walks along the diameter of the garden, which is 7.5 m.

The circumference formula C = πd yields C = 7.5π m.  This is approximately 23.56 m, which we must round up to 24 m, and which calls for 24 - 1 m pieces at $8.99 each.

The desired fencing would cost (24 m)($8.99/m), or $215.76
