2. A circle has a diameter of 5.2 feet. Which

measurement is closest to the circumference of

the circle in feet?

Answer 1

1) Option B - 25.12 ft

2) Option C - 24.1 ft

Explanation:

1) Given : The circular rug has a diameter of 8.2 feet.

To find : Which measurement is closest to the circumference of the rug in feet?

Solution :

The circumference of rug is given by
`C=\pi d`

Where, d is the diameter = 8.2 feet.

`C=3.14* 8.2`

`C=25.748\ ft`

The most closest measurement is 25.12 ft.

Therefore, option B is correct.

2) Given : A circle has a diameter of 5.2 feet.

To find : Which measurement is closest to the circumference of the circle in feet?

Solution :

The circumference of circle is given by
`C=\pi d`

Where, d is the diameter = 5.2 feet.

`C=3.14* 5.2`

`C=16.328\ ft`

The most closest measurement is 24.1 ft.

Therefore, option C is correct.
