Question

Ashton plans to put a fence around his circular garden. When Ashton walks from one side of the garden to the other, through the middle, it is 7.5 metres. Fencing is sold in 1m pieces and costs $8.99 per meter. Find the circumference of the garden. How much will it cost for Ashton's new fence? 2.

Answer 1

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

Total fencing cost: $215.76

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
