The circumference of a circle equals pi times the diameter. Using 3.14 to approximate pi, what is the approximate circumference in inches of a circle with a diameter of 12 in.? (1 point) in.

Answer 1

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

\[ C = \pi \times d \]

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

Given that the diameter \(d\) is 12 inches and using \( \pi \approx 3.14 \):

\[ C \approx 3.14 \times 12 \]

Now, perform the multiplication:

\[ C \approx 3.14 \times 12 = 37.68 \]

Therefore, the approximate circumference of the circle is 37.68 inches.

Answer 2

no

Answer 3

Let's go through the calculation again to ensure it's accurate.

The formula for the circumference of a circle is:

\[ C = \pi \times d \]

Given:

• Diameter \(d = 12\) inches
• Approximation of \(\pi \approx 3.14\)

Calculating the circumference:

\[ C \approx 3.14 \times 12 \]

Now performing the multiplication step-by-step:

\[ 3.14 \times 12 = 37.68 \]

So the approximate circumference of the circle with a diameter of 12 inches is indeed 37.68 inches.
