A museum groundskeeper is creating a semicircular statuary garden with a diameter of 23 feet. There will

be a fence around the garden. The fencing costs $7.50 per linear foot. About how much will the fencing

cost altogether? Round to the nearest hundredth. Use 3.14 for pi

Respuesta :

Answer: $443.32

Step-by-step explanation:

Hi, to answer this question we have to calculate perimeter of a semicircle:

P = π (d/2) + d

Where d is the diameter

Replacing with the values given:

P = 3.14 (23/2) + 23 = 59.11 feet  

Since each linear foot cost $7.50, we have to multiply that cost by the perimeter.

59.11 x 7.50 = $443.32
