How much trim is needed to surround two circular gardens that each have a diameter of 13 feet? Use 3.14 for pi.

To determine how much trim is needed to surround two circular gardens, we need to find the circumference of each garden and then multiply by 2 for the total amount of trim.

The formula for the circumference of a circle is:

\[
C = \pi \times d
\]

where \( C \) is the circumference and \( d \) is the diameter of the circle.

Given:
- Diameter \( d = 13 \, \text{feet} \)
- \( \pi = 3.14 \)

Now, calculate the circumference for one garden:

\[
C = 3.14 \times 13 = 40.82 \, \text{feet}
\]

Since there are two gardens, multiply by 2:

\[
\text{Total trim} = 40.82 \times 2 = 81.64 \, \text{feet}
\]

Thus, **81.64 feet** of trim is needed to surround both gardens.

Here are five related questions for further exploration:
1. What is the area of each circular garden?
2. How would the amount of trim change if the diameter was 15 feet instead?
3. How much trim would be required for three circular gardens of the same size?
4. What would the trim length be for a garden with a diameter of 20 feet?
5. What is the relationship between the diameter and circumference of a circle?

**Tip:** For larger calculations, rounding \(\pi\) to 3.1416 provides a more accurate result.

Find out how much trim is needed to surround two circular gardens, each with a diameter of 13 feet. Learn to apply the circumference formula C = π × d using pi as 3.14. Perfect for Grades 6-8 geometry students.
