how many meters is the circumference of a circle with a radius of 20 cm?

Harman [31]

First find the circumference of the circle.
Circumference: $2 \pi r$

Plug in 20 for the radius (r).
$2 \pi20$ = 125.66

The circumference of the circle is 125.66 cm.
Now to find this in meters... there are 100 centimeters in 1 meter.

Divide 125.66 by 100 to find how many meters this is.
125.66 ÷ 100 = 1.26

The circle's circumference is 1.26 meters.
