The radius of a circle is 41 miles. What is the circle's circumference?

Use ​𝜋 ≈ 3.14 and round your answer to the nearest hundredth.

1 answer

The circumference of a circle can be calculated using the formula:

Circumference = 2 * π * radius

Plugging in the given radius of 41 miles and the approximation of π as 3.14, we get:

Circumference = 2 * 3.14 * 41
Circumference = 2 * 3.14 * 41
Circumference = 6.28 * 41
Circumference ≈ 129.08 miles

Therefore, the circle's circumference is approximately 129.08 miles.
