Question

The diameter of a hat is 6.8 inches. What is the distance around the hat using π = 3.14? Round to the hundredths place.

2.17 inches
10.68 inches
21.35 inches
36.29 inches

Answer 1

21.35 inches

Explanation:

Hello!

The distance around the hat is also called the circumference (the perimeter of a circle). To find this, we use the formula:
`C = 2\pi r`, where r is the radius.

If we don't have a given radius when solving for circumference, we can use the diameter, and then the formula would change to
`C = \pi D` (2r is the same as D), where D is the diameter.

Given that the diameter is 6.8, and the desired value of Pi is 3.14, we can solve for the circumference.

Solve for the Circumference:

• C = πD
• C = (3.14)(6.8)
• C = 21.352 ≈ 21.35

The circumference is approximately 21.35 inches.
