Question

problem 2
tip: you can click the calculator symbol at the top of the screen to bring up desmos at any time!
circumference
circle
$c = 2\pi r$ or $c=pi d$
what is the circumference of a circle with a radius of 1.875 cm.
what is the circumference to the hundredths place.
use the $pi$ symbol on desmos.
11.79 centimeters
44.18 centimeters
12 centimeters
11.78 centimeters

Explanation:

Step1: Identify the formula

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

Step2: Substitute the radius value

Given $r = 1.875$ cm, so $C=2\times\pi\times1.875$.

Step3: Calculate the value

$C = 3.75\pi\approx3.75\times 3.14159 = 11.7809625$.

Step4: Round to hundredths place

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

Answer:

11.78 centimeters
