Question

plz help, Randy is fencing off a semi-circular region in his backyard against a wall. The semi-circular region has a diameter of 24 feet. The fencing will go along the arc only. How much fencing does Randy need?

Answer 1

`Fence = 41.408ft`

Explanation:

Given

`d = 24ft`

Required

Determine the length of the wall

First, we calculate the circumference (C) of the semi-circle

`C =\pi d`

`C = 3.142 * 24`

`C = 75.408`

The length of the fence is calculated by subtracting the diameter from the circumference:

`Fence = C - d`

`Fence = 75.408ft - 24ft`

`Fence = 41.408ft`
