What is the circumference of a circle with a diameter of 16 in?

Answer 1

#C=50. "in"#

The formula for calculating the circumference of a circle is #C=pi * d#, where #pi# is #3.1415...# and #d# is the diameter.
#C=pi * 16"in"=50.265482457437 "in"=50. "in"# (with two significant figures)

Answer 2

#16pi#

We have that the circumference C is #pi*2r# or #pi*d#, that's because #pi# was defined as the ratio between the circumference and the diameter. So, axiomatically:
#C/d = pi#, therefore #C = pi*d#

Answer 3

The circumference of a circle can be found using the formula: Circumference = π * diameter. Substituting the given diameter of 16 inches, we have: Circumference = π * 16 inches. So, the circumference is 16π inches or approximately 50.265 inches.

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.
