What is the circumference of a circle with diameter 32?

Use 3.14 for pi.

Round your answer to the nearest tenth.

The formula for the circumference \( C \) of a circle is:

\[
C = \pi \times d
\]

where \( d \) is the diameter. Given that the diameter is 32 and \( \pi \) is approximately 3.14, the calculation is:

\[
C = 3.14 \times 32 = 100.48
\]

Rounding to the nearest tenth:

\[
C \approx 100.5
\]

So, the circumference is approximately **100.5 units**.

2. How does the circumference change if the diameter is doubled?
3. What is the area of a circle with the same diameter?
4. If the diameter of a circle is halved, what happens to the circumference?
5. How is the circumference related to the radius of the circle?

**Tip:** The circumference of a circle is directly proportional to its diameter, meaning if you double the diameter, you also double the circumference.
