Question

Each circumference is given using the ≈ symbol. What does that mean about

Answer 1

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 = $\frac{d}{2}$ = $\frac{1}{2}$ = 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
