Question

Find the circumference of a circle with diameter 5.42m.

Answer 1

Answer:

17.03 meters

Step-by-step explanation:

The circumference of a circle:

$C=2\pi r \mbox{ or }C=\2d$

where r is the radius and d is the diameter.

Given the diameter here, all you need to do is multiply it by pi:

$\rightarrow C=\pi d\\\rightarrow C=(3.14159...)(5.42)\\\rightarrow C=17.0274...$

Rounded to 2 decimal places, you get 17.03 meters.
