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

1 answer

To find the circumference \( C \) of a circle, you can use the formula:

\[ C = 2\pi r \]

where \( r \) is the radius. Given that the radius \( r = 1.875 \) cm, we can substitute this value into the formula:

\[ C = 2\pi (1.875) \]

Calculating this:

\[ C \approx 2 \times 3.14159 \times 1.875 \approx 11.769 \]

Rounding to the hundredths place:

\[ C \approx 11.77 , \text{cm} \]

So, the circumference of the circle is approximately 11.77 cm.
