Question

A circle has a radius of 26.85 inches. What is the circumference of this circle? Use 3.14 for pi. Round your final answer to the nearest tenth. Enter your answer as a decimal in the box.

Answer 1

Answer:168.6

Explanation:

Answer 2

The circumference formula is

`C=2\pi r`

where r is the radius given to us as 26.85, and pi is to be 3.14. In our formula then, we have

`C=2(3.14)(26.85)`.

Doing that multiplication and rounding to the nearest tenth leaves us with a circumference of 168.6 inches.
