What is the circumference of a circle with a radius of 1.875 cm.

What is the circumference to the hundredths place.

11.79 centimeters

44.18 centimeters

12 centimeters

11.78 centimeters

1 answer

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 is \( 1.875 \) cm, we can calculate the circumference as follows:

\[ C = 2 \times \pi \times 1.875 \]

Using the value of \( \pi \) as approximately \( 3.14159 \):

\[ C \approx 2 \times 3.14159 \times 1.875 \approx 11.78 \text{ cm} \]

To the hundredths place, the circumference of the circle is approximately \( 11.78 \) centimeters.

Among the given options, the correct answer is:

11.78 centimeters.
