Answer: $657.53
Explanation:
Circumference of a circle = πd
But in this case, it's a semi circle, so the circumference will be:
= πd/2
= (3.142 × 31) / 2
= 97.402/2
= 48.701
Then, the total amount of the fencing will be:
= 48.701 + 31
= 79.701
Then, the fencing cost will be:
= 79.701 × $8.25
= $657.53
