Dillon has a round trampoline with a diameter of 4 yards. What is the trampoline's circumference?

Use 3.14 for ​𝜋. If necessary, round your answer to the nearest hundredth.


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

\[
C = \pi \times d
\]

Where \( d \) is the diameter of the circle.

Given:
- Diameter \( d = 4 \) yards
- \( \pi = 3.14 \)

Now, calculate the circumference:

\[
C = 3.14 \times 4 = 12.56 \, \text{yards}
\]

Thus, the circumference of Dillon's trampoline is \( 12.56 \) yards.

Here are 5 related questions:
1. What is the radius of the trampoline?
2. How would the circumference change if the diameter was doubled?
3. What is the area of the trampoline?
4. How does the circumference formula relate to the area of a circle?
5. How would the result differ if you used a more accurate value for \( \pi \)?

**Tip:** Always use the radius or diameter when solving problems involving circles. The radius is half of the diameter.
