An artist used silver wire to make a square that has a perimeter of 40 inches. she then used copper wire to make the largest circle that could fit in the square, as shown below.
square with perimeter of 40 inches
what is the circumference of the copper circle? use 3.14 to represent π.

31.4 in.

Step-by-step explanation:

The perimeter of a square is

P = 4s,

where s is the length of a side.

P = 4s

40 in. = 4s

s = 10 in.

Each side of the square measures 10 in.

The largest circle that fits inside a 10-square has a diameter of 10 inches.

For a circle, the circumference is

C = πd,

where d = diameter

C = πd

C = 3.14 * 10 in.

C = 31.4 in.

38 was the other number of your question.

b and c are the correct answers.

good luck on the quiz! : d
