The circumference of a circle can be calculated using the formula:
Circumference = π * diameter
Given that the diameter of the circle is 5 cm, we can substitute this value into the formula:
Circumference = π * 5 cm
Circumference ≈ 3.14 * 5 cm
Circumference ≈ 15.7 cm
The area of a circle can be calculated using the formula:
Area = π * (radius)^2
Given that the diameter of the circle is 5 cm, the radius is half of the diameter, so the radius is:
radius = diameter / 2
radius = 5 cm / 2
radius = 2.5 cm
Now, we can substitute the radius into the formula:
Area = π * (2.5 cm)^2
Area ≈ 3.14 * (2.5 cm)^2
Area ≈ 3.14 * 6.25 cm^2
Area ≈ 19.625 cm^2

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.
