Question

What is the radius of the circle made by Ana’s sister in the green car? Use 3.14 for pi and round your answer to the nearest tenth. Show your work.

Answer 1

`r=20.1`

Explanation

`C=\pi d`

Green car circumfrence = 126 feet

Plug in numbers

`126=3.14d`

Divide both sides by 3.14

`(126)/(3.14) = 40.12...`

Divide diameter by 2 to find radius

`(40.1)/(2) = 20.05`

round up to
`20.1`
