Answer 1

Answer:

1) Option B - 25.12 ft

2) Option C - 24.1 ft

Step-by-step 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.

 $C=3.14\times 8.2$

 $C=25.748\ ft$

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.

 $C=3.14\times 5.2$

 $C=16.328\ ft$

The most closest measurement is 24.1 ft.

Therefore, option C is correct.
