Question

1. What is the circumference of the circle below? Use 3.14 for pi and Round

your answer to the nearest tenth.

Answer 1

`C = 34.5 \ cm`

Explanation:

Circumference of the circle is given as

`C=2\pi r`

Where r is radius of circle.

Diameter of given circle is 11 cm. We know radius is half of diameter.

`r=(d)/(2) = (11)/(2)`

Circumference can be calculated as

`C=2\pi ((11)/(2) )`

`C = 34.5 \ cm`
