Question

A museum is creating a simicircle statuary garden with a diameter of 26 feet. There will be a fence around the garden. The fencing costs $8.25 per linear foot. About how much will the fencing cost altogether.

Answer 1

Answer: $336.77

Explanation:

So, the fencing is technically the perimeter, so we have to find the perimeter of the semicircle.

Perimeter of a semicircle = 2(pi)(r)/2

So, divide 26 by 2 to get the radius, which is 13.

(We will use 3.14 for pi)

Then fill in the variables 2 x (3.14) x (13) / 2

So, when you multiply all the numbers you will get 81.64/2.

81.64/2 = 40.82 ft.

Now that you have found how much feet the fencing will be, multiply it by the cost.

40.82 x 8.25 = 336.765.

Round your final answer by the nearest hundredth which is 336.77.
