Question

The radius of a circle is 6.1 kilometers. What is the circle's circumference?

Use 3.14 for r and round your answer to the nearest hundredth.

Answer 1

I believe there's a mistake in the question, as "r" usually stands for "radius" and not the value of pi. Assuming you meant to ask for the circumference, the correct formula would be:

Circumference = 2πr

where r is the radius of the circle and π (pi) is a mathematical constant approximately equal to 3.14.

Using this formula and the given radius of 6.1 kilometers, we get:

Circumference = 2 x 3.14 x 6.1

Circumference = 38.284 kilometers (rounded to the nearest hundredth)

Therefore, the circumference of the circle with a radius of 6.1 kilometers is approximately 38.28 kilometers.
