Answer:
Circumference ≈ 3.142 cm
Step-by-step explanation:
≈ basically means that it's an approximate value.
The formula to find the circumference of a circle is:
Circumference = 2πr
The diameter is given, but we can find the radius by halving the diameter.
radius = =
= 0.5 cm
Now that we know the radius, we can add the radius into the formula and find the circumference.
Circumference = 2 × π × 0.5
Circumference = π × 1
Circumference ≈ 3.142 cm
