The students in Mrs. Griffith's kindergarten class sit down in a circle for show-and-tell. The circle they form has a diameter of 6 feet. What is the circle's circumference?

Answer 1

To find the circumference of a circle, you can use the formula:

\[ C = \pi d \]

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

Given that the diameter \( d = 6 \) feet, we substitute the diameter into the formula:

\[ C = \pi \times 6 \]

Using the approximation \( \pi \approx 3.14 \):

\[ C \approx 3.14 \times 6 = 18.84 \text{ feet} \]

Therefore, the circumference of the circle is approximately \( 18.84 \) feet.

If you were to use a more precise value for \( \pi \), you would simply leave the answer in terms of \( \pi \):

\[ C = 6\pi \text{ feet} \approx 18.84 \text{ feet} \]

Thus, the final answer for the circumference of the circle is:

\[ \boxed{18.84} \text{ feet} \]
