Question

What is the approximate circumference of a circle whose diameter is 2.2 m?

Use 3.14 for π and round your answer to the nearest tenth.

6.9m
15.2m
13.8m
7.6m

Answer 1

6.9 m

Explanation:

r = Radius of circle

d = diameter of circle

π = 3.14

Circumference of circle =
`2\pi r`

=
`\pi d`

=
`(3.14)(2.2)` m

= 6.908 m

= 6.9 m (Rounded to the nearest tenth)
