The circumference of a circle can be found using the formula: ( C = \pi \times d ), where ( C ) is the circumference and ( d ) is the diameter.

Given that the diameter of the circle is 4 inches, substitute ( d = 4 ) into the formula: [ C = \pi \times 4 ]

Thus, the circumference of the circle is ( 4\pi ) 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.

- Cups A and B are cone shaped and have heights of #32 cm# and #12 cm# and openings with radii of #5 cm# and #8 cm#, respectively. If cup B is full and its contents are poured into cup A, will cup A overflow? If not how high will cup A be filled?
