Question

C = [?] ft.
7 ft.
Shape: Circle
What is circumference of a circle with a diameter of 7 feet?
C = πd
Use 3.14 for π

Answer 1

To calculate the circumference \( C \) of a circle using the formula \( C = \pi d \), where \( d \) is the diameter, we can substitute the values given:

1. The diameter \( d = 7 \) ft.
2. We use \( \pi \approx 3.14 \).

Now plug in the values:

\[
C = \pi d = 3.14 \times 7
\]

Calculating that:

\[
C = 3.14 \times 7 = 21.98 \text{ ft}
\]

Thus, the circumference of the circle is approximately:

\[
C \approx 21.98 \text{ ft}
\]
