The formula for the circumference \( C \) of a circle is given by:
\[ C = 2\pi r \]
where \( r \) is the radius of the circle. Given that the radius \( r \) is 7 cm, we can substitute this value into the formula:
\[ C = 2\pi \times 7 \approx 2 \times 3.14 \times 7 \]
Calculating this,
\[ C \approx 2 \times 3.14 \times 7 \approx 43.96 \]
Rounding this to the nearest whole number, the circumference is approximately:
\[ 44 \text{ cm} \]
So, the circumference of the circle is 44 cm.
