Question

6. The half-circular garden, shown below, is 12 ft from A to B. You decide to walk from point A to point B

around the circular part of the garden.

c. What would be the distance if you walked around the entire garden?
Answer:

Answer 1

30.857 feet

Explanation:

It is given that the diameter of the half-circular garden is 12 feet.

Therefore, the perimeter of the garden will be = length of the half-circular arc + diameter of the garden.

Now, length of the half-circular arc = πr

Given Diameter = 12 ft.

So, radius = 6 ft.

So, length of the half-circular arc = πr =
`(22 * 6)/(7) =18.857` feet.

Hence, perimeter of the garden = 18.857 + 12 = 30.857 feet.

Therefore, 30.857 feet distance will be covered if I walk around the entire garden. (Answer)
