The radius of a circle is 5.5 cm. What is the circumference in meters?

Answer 1

C = 0.11#pi# or 0.3456 m

To find circumference of a circle when you have the radius, you use the formula C = 2#pi#r. In this question r = 5.5 cm but because we want centimeters, we use r = 0.055 m. C = 20.055#pi# = 11#pi#. Some teachers let you leave #pi# in the answer, if they don't, it multiplies out to 0.3456 m.

34.55 cm or.345 meters

Radius is 5.5 cm. Circumference = pi x diamter ( diameter of a circle is the radius x 2) C=Pi x 11 C=34.55cm/ 100 (because there are 100 cm in meter} C=.345m

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
