How do you find the circumference of a circle with a diameter of 4.4 cm?

Answer 1

Use the formula #c=pid# to obtain circumference #~=13.823#

The constant #pi# is the ratio of the circumference of a circle to its diameter (i.e. #pi = c/d#) or more commonly #c =pi*d# (where #c# is the circumference and #d# is the diameter).

You can use a calculator to evaluate this (if your calculator does not have the constant #pi# assigned to a button, you can use #3.14159# which is a reasonable approximation for virtually all situations)

To find the circumference of a circle, you can use the formula: Circumference = π × Diameter. Given a diameter of 4.4 cm, you can substitute this value into the formula and calculate the circumference using the approximation of π as 3.14.

Circumference = 3.14 × 4.4 cm Circumference ≈ 13.816 cm

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.
