what is the circumference of a circle with a radius of 1.875 cm.
what is the circumference to the hundredths place.
use the π symbol on desmos.
11.79 centimeters
44.18 centimeters
12 centimeters
11.78 centimeters

Explanation:

Step1: Recall the formula for circle - circumference

The formula for the circumference of a circle is $C = 2\pi r$, where $r$ is the radius of the circle.

Step2: Substitute the given radius value

Given $r = 1.875$ cm. Substitute $r$ into the formula: $C=2\pi\times1.875$.

Step3: Calculate the value

$C = 2\times\pi\times1.875=3.75\pi$. Using the $\pi$ symbol on a calculator (Desmos), $C\approx3.75\times 3.14159 = 11.7809625$.

Step4: Round to the hundredths place

Rounding $11.7809625$ to the hundredths place gives $11.78$ cm.

Answer:

$11.78$ centimeters
