The firmly packed soil surrounding a potted plant has a diameter of 11 inches.

If the potted plant and soil are to be planted in the ground in a hole just big enough to fit the plant and soil, which measurement provides the closest approximation for the circumference of the hole that must be dug?

Use 3.14 for π
.
A.11.2 inches
B.17.3 inches
C.34.5 inches
D.69.1 inches

The circumference of a circle can be calculated using the formula:

\[
C = \pi \times d
\]

Where:
- \( C \) is the circumference
- \( \pi \) is approximately 3.14
- \( d \) is the diameter of the circle

Given that the diameter of the potted plant and soil is 11 inches, we can calculate the circumference as follows:

\[
C = 3.14 \times 11 = 34.54 \text{ inches}
\]

The closest approximation to 34.54 inches is **34.5 inches**, which corresponds to option **C**.

Thus, the answer is **C. 34.5 inches**.
