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

The distance around the hat is equal to the circumference of the circle with diameter 6.8 inches.

The formula for the circumference of a circle is:

circumference = π × diameter

Substituting the given values, we get:

circumference = 3.14 × 6.8

circumference ≈ 21.35

Rounding to the hundredths place, we get the final answer as:

circumference ≈ 21.35 inches

Therefore, the distance around the hat using π = 3.14 is approximately 21.35 inches.
