To find the circumference of a circle, you can use the formula:
\[ C = 2\pi r \]
where \( C \) is the circumference and \( r \) is the radius.
For a circle with a radius of 1.875 cm:
\[ C = 2\pi(1.875) \]
Calculating this:
1. Multiply the radius by 2:
\[ 2 \times 1.875 = 3.75 \]
2. Now multiply that result by \(\pi\):
\[ C \approx 3.75 \times 3.14159 \approx 11.769 \text{ cm} \]
To round this to the hundredths place, we take the first two decimal places:
\[ C \approx 11.77 \text{ cm} \]
So the circumference of the circle with a radius of 1.875 cm is approximately **11.77 cm**.
