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

measurement is closest to the circumference of

the circle in feet?

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

Where, d is the diameter = 8.2 feet.

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

Where, d is the diameter = 5.2 feet.

The most closest measurement is 24.1 ft.

Therefore, option C is correct.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
