A circular garden with a radius of 8 feet is surrounded by a circular path with a width of 3 feet.

What is the approximate area of the path alone? Use 3.14 for [tex]\pi[/tex].

A. [tex]172.70 \, \text{ft}^2[/tex]
B. [tex]178.98 \, \text{ft}^2[/tex]
C. [tex]200.96 \, \text{ft}^2[/tex]
D. [tex]379.94 \, \text{ft}^2[/tex]

To solve the problem of finding the approximate area of the path alone, let's follow these steps:

1. Determine the total radius: The radius of the garden is given as 8 feet. The path around the garden adds another 3 feet to this radius. Therefore, the total radius (from the center of the garden to the outer edge of the path) is:
[tex]\[ \text{Total radius} = \text{Radius of the garden} + \text{Width of the path} = 8\, \text{feet} + 3\, \text{feet} = 11\, \text{feet} \][/tex]

2. Calculate the area of the larger circle (garden + path): Using the total radius of 11 feet, we can find the area of the larger circle. The formula for the area of a circle is [tex]\( \pi r^2 \)[/tex]:
[tex]\[ \text{Area of the larger circle} = \pi \times (11\, \text{feet})^2 = 3.14 \times 121\, \text{feet}^2 = 379.94\, \text{feet}^2 \][/tex]

3. Calculate the area of the garden alone: Next, we use the radius of just the garden, which is 8 feet, to calculate the area of the garden alone:
[tex]\[ \text{Area of the garden} = \pi \times (8\, \text{feet})^2 = 3.14 \times 64\, \text{feet}^2 = 200.96\, \text{feet}^2 \][/tex]

4. Calculate the area of the path alone: The area of the path is the difference between the area of the larger circle (garden + path) and the area of the garden:
[tex]\[ \text{Area of the path} = \text{Area of larger circle} - \text{Area of garden} = 379.94\, \text{feet}^2 - 200.96\, \text{feet}^2 = 178.98\, \text{feet}^2 \][/tex]

Therefore, the approximate area of the path alone is [tex]\( 178.98 \, \text{ft}^2 \)[/tex]. The correct answer is:
[tex]\[ \boxed{178.98 \, \text{ft}^2} \][/tex]
