Question

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

answers:

11.79

44.18

12

11.78

Answer 1

are your sure its 11.79?

Answer 2

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

\[
C = 2 \pi r
\]

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

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

Using \( \pi \approx 3.14159 \), we can calculate the circumference:

\[
C \approx 2 \times 3.14159 \times 1.875 \approx 11.785
\]

Rounding this to the hundredths place gives us:

\[
C \approx 11.79 \, \text{cm}
\]

So, the circumference of the circle to the hundredths place is **11.79 cm**.

Answer 3

Let's double-check the calculation for clarity.

The formula for the circumference \( C \) of a circle is given by:

\[
C = 2 \pi r
\]

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

1. Calculate \( 2 \times 1.875 \):
\[
2 \times 1.875 = 3.75
\]

2. Now multiply by \( \pi \) (using \( \pi \approx 3.14159 \)):
\[
C \approx 3.75 \times 3.14159 \approx 11.786
\]

3. Rounding \( 11.786 \) to the hundredths place gives us **11.79**.

So, yes, I confirm that the circumference of the circle with a radius of 1.875 cm is approximately **11.79 cm** to the hundredths place.
