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

What is the circumference to the hundredths place.

1 answer

The circumference \( C \) of a circle can be calculated using the formula:

\[ C = 2 \pi r \]

where \( r \) is the radius of the circle.

In this case, the radius \( r \) is 1.875 cm. Plugging this value into the formula gives:

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

Calculating this gives:

\[ C \approx 2 \times 3.14159 \times 1.875 \approx 11.7691 \text{ cm} \]

Rounding to the hundredths place, the circumference is approximately:

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

So, the circumference of the circle is 11.77 cm.
