Answer 2

Hello:

--> find circumference to the nearest tenth

Our formula for the circumference of the circle:

`\text{Circumference}=2\pi r`

-'r': radius's length --> 13.4

Let's calculate:

`\text{Circumference}=2*\pi *13.4=26.8\pi =84.19 \text{ inches}`

Our circumference rounded to the nearest tenth ==> 84.2 inches

Answer: 84.2 inches
