Greg installed a circular drain that has a diameter of 4.8 inches.
To the nearest tenth of an inch, what is circumference of the drain?

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

\[
C = \pi \times d
\]

where \( d \) is the diameter.

Given the diameter \( d = 4.8 \) inches, we can substitute it into the formula:

\[
C = \pi \times 4.8
\]

Using \( \pi \approx 3.1416 \), we get:

\[
C \approx 3.1416 \times 4.8 \approx 15.1 \text{ inches}
\]

So, the circumference of the drain is approximately **15.1 inches**.

2. What would the circumference be if the diameter was doubled?
3. How does changing the diameter affect the circumference?
4. What is the relationship between the radius and the circumference of a circle?
5. If the radius was given instead of the diameter, how would you find the circumference?

**Tip**: Always remember that the diameter is twice the radius when calculating properties of circles!
