Question

What is the circumference of the following figure? Be sure to convert your answer to yards. 56.52 yd 1.57 yd 4.71 yd 28.26 yd

Answer 1

1.57 yd is the right one just did this one

Explanation:

Answer 2

`1.57\textrm{ yd}`

Explanation:

Given:

Diameter of the circle,
`D=18\textrm{ in}`.

We need to convert the diameter in yards.

We know that,
`36\textrm{ in} = 1\textrm{ yd}`

So,
`1\textrm{ in} =(1)/(36)\textrm{ yd}`

Now,
`18\textrm{ in} =(1)/(36)* 18=0.5\textrm{ yd}`

Circumference of a circle of diameter,
`D`, is given as:

`\textrm{Circumference}=\pi D`

Plug in 0.5 for
`D` and calculate the circumference. This gives,

`\textrm{Circumference}=\pi * 0.5=3.14* 0.5=1.57\textrm{ yd}`

Therefore, the circumference of the given figure is
`1.57\textrm{ yd}`.
